This reverts commit a3e4adf274f86b2363fedaa964297cb38526cef0.
As pointed by Andread Oberritter <obi@linuxtv.org>:
That's wrong, because the array size is DTV_MAX_COMMAND + 1.
Using the ARRAY_SIZE macro instead might reduce the confusion.
Also, changeset 3995223038 already fixed this issue.

The cx88 driver would force core->input to always be zero when doing the
the request_acquire(). While it wasn't actually changing the input register
in the hardware, the driver makes decision based on the current input. In
particular, it decides whether to do things like enabling the comb filter
when on a composite input but disabling it on s-video. So for example, on
the HVR-1300, using the s-video input with the MPEG encoder would end up with
the video decoder core configured as though the input type were composite.
In short, the driver state did not match the hardware state.
This patch does two things:
1. It forces the input to zero only if actually switching to DVB mode. This
prevents the input from changing when the blackbird driver opens the device.
2. Keep track of what the input was set to when switching to DVB, and reset
it back when done. This eliminates a condition where for example the user
had the analog side of the board set to capture on the s-video input, then
he used DVB for a bit, then the analog input would unexpectedly be set to
the tuner input.

This is admittedly a bit of a hack, but if we change our timeout value
to something longer and fudge our synthesized trailing space sample
based on the initial pulse sample, rc-core decode continues to work just
fine with both rc-6 and rc-5, and now lirc userspace decode shows proper
repeats for both of those protocols as well. Also tested NEC
successfully with both decode options.
We do still need a reset timer callback using the hardware's timeout
value to make sure we actually process samples correctly, regardless of
our somewhat hacky timeout and synthesized trailer above.
This also adds a missing del_timer_sync call to the module unload path.

This is a custom IR protocol decoder, for the RC-6-ish protocol used by
the Microsoft Remote Keyboard, apparently developed internally at
Microsoft, and officially dubbed MCIR-2, per their March 2011 remote and
transceiver requirements and specifications document, which also touches
on this IR keyboard/mouse device.
Its a standard keyboard with embedded thumb stick mouse pointer and
mouse buttons, along with a number of media keys. The media keys are
standard RC-6, identical to the signals from the stock MCE remotes, and
will be handled as such. The keyboard and mouse signals will be decoded
and delivered to the system by an input device registered specifically
by this driver.
Successfully tested with multiple mceusb-driven transceivers, as well as
with fintek-cir and redrat3 hardware. Essentially, any raw IR hardware
with enough sampling resolution should be able to use this decoder,
nothing about it is at all receiver-hardware-specific.
This work is inspired by lirc_mod_mce:
The documentation there and code aided in understanding and decoding the
protocol, but the bulk of the code is actually borrowed more from the
existing in-kernel decoders than anything. I did recycle the keyboard
keycode table, a few defines, and some of the keyboard and mouse data
parsing bits from lirc_mod_mce though.
Special thanks to James Meyer for providing the hardware, and being
patient with me as I took forever to get around to writing this.

In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3
small issues:
1) When the 'fw' variable goes out of scope we'll leak the memory
allocated to it by request_firmware() by neglecting to call
release_firmware().
2) After a successful request_firmware() we allocate fw->size bytes
of memory using kzalloc() only to immediately overwrite all that
memory with memcpy(), so asking for zeroed memory seems like wasted
effort - just use kmalloc().
3) In one of the error messages "no memory" lacks a space and is
written as "nomemory".

The Marvell camera core can support all three videobuf2 buffer modes, which
is slick, but it also requires that all three modes be built and present,
even though only one is likely to be used. This patch allows the supported
modes to be selected at configuration time, reducing the footprint of the
driver. Prior to this patch, the MMP camera driver looked like this:
mmp_camera 19092 0
videobuf2_core 15542 1 mmp_camera
videobuf2_dma_sg 3173 1 mmp_camera
videobuf2_dma_contig 2188 1 mmp_camera
videobuf2_vmalloc 1718 1 mmp_camera
videobuf2_memops 2100 3 videobuf2_dma_sg,videobuf2_dma_contig,videobuf2_vmalloc
Afterward, instead, with scatter/gather only configured:
mmp_camera 16021 0
videobuf2_core 15542 1 mmp_camera
videobuf2_dma_sg 3173 1 mmp_camera
videobuf2_memops 2100 1 videobuf2_dma_sg
The total goes from 43,813 bytes to 36,836.
The emphasis has been on simplicity and minimal #ifdef use rather than on
squeezing out every possible byte of code. For configuration, the driver
simply looks at which videobuf2 modes have been configured in and supports
them all; it's simplistic but should be good enough.
The cafe driver is set to support vmalloc and dma-contig; mmp supports only
dma-sg, since that's the only mode that really makes sense to use.

The driver is too limited: it assumes that UIO is used only for
controlling the antenna, and that only UIO-1 is in usage. However,
from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems
that H7 needs to use all 3. So, make the code generic enough to handle
the most complex scenario. For now, only antena GPIO can be specified,
but is is easier now to add the other GPIO/UIO needs.

This driver is very big and complex. An error happening in the middle
of any initialization may cause the frontend to not work. So, it
needs to properly propagate error codes internally and to userspace.
Also, printing the error codes at the places it happened helps to
discover were's a bug at the code.
Before this change, a do { } while (0) loop and lots of breaks inside
were used to propagate errors. While this works, if there are
loops inside other loops, it could be easy to forget to add another
break, causing the error to not abort the function.
Also, as not all functions were reporting errors, it is hard to
discover why something failed.

The normal 16-bits read routine is called as "Read16_0". This is
due to a flags that could optionally be passed. Yet, on no places
at the code, a flag is passed there.
The same happens with 16-bits write and 32-read/write routines,
and with WriteBlock.
Also, using flags, is an exception: there's no place currently using
flags, except for an #ifdef at WriteBlock.
Rename the function as just "read16", and the one that requires flags,
as "read16_flags".

As the CI requires a continuous data stream, the driver inserts dummy
packets when necessary. Do not pass these packets to userspace anymore.

By default no control events are sent to the application that caused the
control value or flags change (i.e. the control(s) passed to VIDIOC_S_CTRL
or VIDIOC_S_EXT_CTRLS). But if a change in one control causes a change in
another control that was not part of the control(s) in VIDIOC_S_CTRL or
S_EXT_CTRLS, then the application should be notified.

This makes the API for this:

2) match that of the UVC Logitech QuickCam Sphere models
For now this operates in parellel to the sysfs interface for this, but the
intend is to deprecate the sysfs interface and remove it.

Doing a bunch of initialization every time /dev/video is opened, and thus
for example when the udev rules probe for capabilities makes no sense,
do it at driver load, resp. stream start instead.
This is a preparation patch for allowing multiple opens of the /dev/video
node.
