48723543af V4L/DVB (7893): xc5000: bug-fix: allow multiple devices in a single system
The current code passes a context pointer in the xc5000_config struct.
This context pointer is used in the tuner_callback function, used to
reset the device after firmware download.

The xc5000_config struct is a static structure, whose .priv member was
being assigned before calling xc5000_attach().  If there are more than
one of the same device type installed on a single system, the last one
to assign xc5000_config.priv will "win", and all others will cease to
function properly.

This patch passes the context pointer in xc5000_attach() rather that
storing it within the static struct xc5000_config.

07c87a833e V4L/DVB (7891): cx18/ivtv: fix open() kernel oops
Upon error conditions in cx18/ivtv_probe(), the code at the 'err:' label
leaves a NULL entry in cx18/ivtv_cards[]. This can cause a NULL pointer
de-reference in cx18/ivtv_v4l2_open() which is fixed by this patch.

  make: *** [drivers] Error 2

with this config:

   http://redhat.com/~mingo/misc/config-Sat_May__3_16_08_39_CEST_2008.bad

the bug was that the driver uses GPIO functionality but only includes
the GPIO interface definitions for the CONFIG_MT9M001_PCA9536_SWITCH
case, which was not set in this config.

The quick fix seems to be to include linux/gpio.h unconditionally. (this
seems like a small cleanup as well as it removes and #ifdef is more
robust than an inclusion of asm/gpio.h) Not tested too much yet, so
please have another look in any case.

755a18baad V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvb
Since:
1) FW_LOADER is defined as:

config FW_LOADER
        tristate "Userspace firmware loading support"
        depends on HOTPLUG

2) several V4L/DVB driver just selects it;

3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.

So, All drivers that select FW_LOADER should also depend on HOTPLUG.

An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:

drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->

dc9d522a13 V4L/DVB (7836): cinergyT2 build fix
x86.git testing found the following build bug in v2.6.26-rc1:

  drivers/built-in.o: In function `cinergyt2_probe':
  cinergyT2.c:(.text+0xb6117): undefined reference to `input_allocate_device'
  cinergyT2.c:(.text+0xb6230): undefined reference to `input_register_device'
  cinergyT2.c:(.text+0xb623d): undefined reference to `input_free_device'

with the following config:

  http://redhat.com/~mingo/misc/config-Sun_May__4_22_06_54_CEST_2008.bad

The reason for the bug is that the cinergyT2 driver depends on
CONFIG_INPUT functionality, but if INPUT is modular it's still possible
to build CONFIG_DVB_CINERGYT2=y - which leads to missing symbols.

The solution is to make DVB_CINERGYT2 dependent on INPUT.

[ This solves the build problem - i have not tested the driver on this card. ]

71a35fe2a3 V4L/DVB (7830): dvb_ca_en50221: Fix High CPU load in 'top' due to budget_av slot polling
This change addresses kernel bug #10459: In kernel 2.6.25 the
budget_av driver polls for an CI slot in 100ms intervals (because no
interrupt solution for budget_av cards is feasible due to HW reasons).
If no CI/CAM is connected to the DVB card, polling times out only after 250ms.
This periodic polling leads to high CPU load.

The change increases the polling interval for empty slots from 100ms to 5s.
Intervals for remaining slot states (invalid, in progress, ready) are unchanged,
as they are either temporary conditions or no timeout should occur.

fa146c6dce V4L/DVB (7829): cx23885: remove remaining references to dvb-pll
The cx23885 driver used to use dvb-pll for LG-TDVS-H064F support on the
FusionHDTV5 Express.  This has since been converted to use tuner-simple
instead, once digital tuning support was added to tuner-simple.

Since cx23885 no longer uses dvb-pll, remove the #include "dvb-pll.h",
and the DVB_PLL Kconfig selection.

f7c83a0aaa Fix drivers/media build for modular builds
Fix allmodconfig build bug introduced in latest -git by commit
7c91f0624a ("V4L/DVB(7767): Move tuners to common/tuners"):

  LD      kernel/built-in.o
  LD      drivers/built-in.o
  ld: drivers/media/built-in.o: No such file: No such file or directory

which happens if all media drivers are modular:

  http://redhat.com/~mingo/misc/config-Wed_Apr_30_09_24_48_CEST_2008.bad

In that case there's no obj-y rule connecting all the built-in.o files and
the link tree breaks.

The fix is to add a guaranteed obj-y rule for the core vmlinux to build.
(which results in an empty object file if all media drivers are modular)

a8b1ecf3d5 fix irq flags in saa7134
Some files in the drivers/media/video/saa7134 directory uses "int" for flags.
This can cause hard to find bugs on some architectures.  This patch converts
the flags to use "long" instead.

This bug was discovered by doing an allyesconfig make on the -rt kernel where
checks are done to ensure all flags are of size sizeof(long).

the problem is caused by the drivers/media/common/tuners/ subdirectory
not being part of the kbuild hierarchy anymore, due to commit

this seems similar to the problem also reported by Mike Galbraith.

7c91f0624a V4L/DVB(7767): Move tuners to common/tuners
There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.

Kconfig items were rearranged, to split V4L/DVB core from their drivers.

c117d05cd4 V4L/DVB (7753): saa7134: fix tuner setup
Tuner setup were happening during i2c attach callback. This means that it would
happen on two conditions:

        1) if tuner module weren't load, it will happen at request_module("tuner");

        2) if tuner is not compiled as a module, or it is already loaded
           (for example, on setups with more than one tuner), it will happen
           when saa7134 registers I2C bus.

Due to that, if tuner were loaded, tuner setup will happen _before_ reading
the proper values at tuner eeprom. Since set_addr refuses to change for a tuner
that were previously defined (except if the tuner_addr is set), this were
making eeprom tuner detection useless.

This patch removes tuner type setup from saa7134-i2c, moving it to the proper
place, after taking eeprom into account.

Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

This patch contains the following cleanups and fixes:
- "debug" is definitely not a good name for a global variable,
  renamed it to "au0828_debug"
  this fixes a compile error with some kernel configurations
- since the module parameter is int the variable shouldn't be unsigned
- remove the {usb,bridge,i2c}_debug module parameters since they are
  already covered by the "debug" module parameter
- remove the unused au0828_bcount
- make the needlessly global i2c_scan static
- make the needlessly global dvb_register() static

set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't

This patch changed set_addr printk to print a message only if set_addr is
wrong.

It also fix printk at set_type, since, if an attach were failing, nothing
were reported.

With the current code, working or not, a call to set_addr will produce a debug
printk.

also, set_type() were producing a false error message on tuner_xc2028, since
it were requesting for setting a frequency on a place where firmware name

d2b213f7b7 V4L/DVB (7729): Fix VIDIOCGAP corruption in ivtv
Frank Bennett reported that ivtv was causing skype to crash. With help
from one of their developers he showed it was a kernel problem.
VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names
that are too long and does not truncate them so corrupts a few bytes of
the app data area.

Possibly the names also want trimming but for now this should fix the
corruption case.

49844c291a V4L/DVB (7715): pvrusb2: Clean out all use of __FUNCTION__
Apparently the kernel developers no longer consider it proper
etiquette to use __FUNCTION__; everyone must instead use __func__
(even though it breaks with older compilers).  And worse still, actual
effort is being expended to sweep this change throughout the kernel
source tree.  Don't these people have better things to do?  So...
Completely clean out all use of __FUNCTION__ from the pvrusb2 driver
(it was just in the sysfs interface).  I'm not going to use __func__
either.  So there.

18ecbb4771 V4L/DVB (7714): pvrusb2: Fix hang on module removal
The pvrusb2 driver was getting had by this scenario:

1. Task A calls kthread_stop() for task B.
2. Before exiting, then Task B calls kthread_stop() for task C.

The problem is, kthread_stop() wants to allocate an internal resource
to itself (i.e. acquire a lock), which won't be released until
kthread_stop() returns.  But kthread_stop() won't return until task B
is dead.  But task B won't die until it finishes its call to
kthread_stop() for task C, and that will block waiting on the resource
already allocated inside task A.  Deadlock.

With the pvrusb2 driver, task A is the caller to pvr_exit(), task B is
the control thread run inside of pvrusb2-context.c, and task C is any
worker thread run inside of pvrusb2-hdw.c.

This problem got introduced by the previous threading setup change,
which was itself an attempt to fix a module tear-down race (which it
actually did fix).  The lesson here is that a task being waited on as
part of a kthread_stop() simply cannot be allow to also issue a
kthread_stop() - or we make sure not to issue the enclosing
kthread_stop() until we know that the inner kthread_stop() has
completed first.  The solution for the pvrusb2 driver is some hackish
code which changes the main control thread tear down into a two step
process.  This then makes it possible to delay issuing the
kthread_stop() on the control thread until after we know that
everything has been torn down first.  (And yes, we really need that
kthread_stop() because it's the only way to safely guarantee that a
module-referencing kernel thread has safely returned back out of the
module before we finally remove the module.)

If a disconnect happens before initialization is completed, the
pvrusb2 driver can accidentally touch dangling pointers.  The whole
initialization function must be protected by the big_lock, and once
inside that lock, the initialization function should abort if it is
discovered that a disconnect has already taken place.

e5be15c638 V4L/DVB (7711): pvrusb2: Fix race on module unload
The pvrusb2 driver - for basically forever - was not enforcing a
proper module tear-down.  Kernel threads are used inside the driver
and all must be gone before the module can be safely removed.  This
changeset reimplements a chunk of pvrusb2-context.c to enforce this
correctly.  Unfortunately this is not a simple fix.  The new
implementation also cuts back on kernel thread usage; instead of there
being 1 control thread per instance now it's just 1 control thread
shared by all instances.  (By dropping to a single thread then the
module exit function can block on its shutdown and the thread itself
can monitor and cleanly shut down all of the other instances first.)

Implement timed measurement of encoder operation for the first time it
is run.  This allows the driver to note when the encoder has been run
successfully for at least 1/4 second.  On top of that implement
various bits to ensure that the encoder has been run once before
digital streaming for OnAir devices.  This is done via several core
state machine tweaks.
