96a3e79edf drivers: update to pl2303 usb-serial to support Motorola cables
Added 0x0307 device id to support Motorola cables to the pl2303 usb
serial driver. This cable has a modified chip that is a pl2303, but
declares itself as 0307. Fixed by adding the right device id to the
supported devices list, assigning it the code labeled
PL2303_PRODUCT_ID_MOTOROLA.

5620b5f7f1 USB serial: add missing .usb_driver field in serial drivers
This patch (as1443) fixes a bug found in many of the USB serial
drivers: They don't set the .usb_driver field in their
usb_serial_driver structure.  This field is needed for assigning
dynamic IDs for device matching.

In addition, starting with the 2.6.37 kernel, the .usb_driver field is
needed for proper autosuspend operation.  Without it, attempts to open
the device file will fail.

cc604ddd11 USB: ehci-fsl: Fix 'have_sysif_regs' detection
Previously a check was done on an ID register at the base of a CPU's
internal USB registers to determine if system interface regsiters were
present.  The check looked for an ID register that had the format
ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to
determine if a MPC5121 or MPC83xx/85xx was being used.

There are two issues with this method:
- The ID register is not defined on the MPC83xx/85xx CPUs, so its
  unclear what is being checked on them.
- Newer CPUs such as the P4080 also don't document the ID register, but
  do share the same format as the MPC5121.  Thus the previous code did
  not set 'have_sysif_regs' properly which results in the P4080 not
  properly initializing its USB ports.

Using the device tree 'compatible' node is a cleaner way to determine if
'have_sysif_regs' should be set and resolves the USB initialization issue
seen on the P4080.

Tested on a P4080-based system and compile tested on mpc512x_defconfig
with Freescale EHCI driver enabled.

ad84e4a9ef USB: g_printer: fix bug in module parameter definitions
This patch (as1442) fixes a bug in g_printer: Module parameters should
not be marked "__initdata" if they are accessible in sysfs (i.e., if
the mode value in the module_param() macro is nonzero).  Otherwise
attempts to access the parameters will cause addressing violations.

Character-string module parameters must not be marked "__initdata"
if the module can be unloaded, because the kernel needs to access the
parameter variable at unload time in order to free the
dynamically-allocated string.

used to compute the size in a dma_alloc_coherent() call, but then it

allocation.  Fix the problem by adjusting ehci->periodic_size before

f9b07897c6 m68k: Uninline strchr()
Some versions of gcc replace calls to strstr() with single-character
"needle" string parameters by calls to strchr() behind our back.

If strchr() is defined as an inline function, this causes linking errors
like

	ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined!

As m68k is the only architecture that has an inline strchr() and this
inline version is not an optimized asm version, uninline strchr() and use
the standard out-of-line C version in lib/string.c instead.

This also decreases the defconfig/allmodconfig kernel image sizes by a few
hundred bytes.

233d84c46c ALSA: Xonar, CS43xx: Don't overrun static array
'cs4398_regs' in 'struct xonar_cs43xx' is an array of 'u8' with a size of
8. So, this code in sound/pci/oxygen/xonar_cs43xx.c::dump_d1_registers()

    		for (i = 2; i <= 8; ++i)
	  			snd_iprintf(buffer, " %02x", data->cs4398_regs[i]);

will overrun the array when 'i == 8'.

I guess that what's needed to fix it is the trivial patch below, but I
must admit that I have no idea about this code, so I may very well be
wrong. Additionally, I have no way to actually test this, so all I know is
that the below compiles. Someone who actually knows this code should take
a look before anything is comitted - consider the below (not much more
than) a bug report.

Rework implementation so that suspend only stores config, and sets

d062d44a83 staging: brcm80211: remove assert to avoid panic since 2.6.37 kernel
The driver assumed it would receive skb packets from MAC80211 which
are not cloned. To guard this assumption an assert was placed in
the transmit routine. As of kernel 2.6.37 it turns out MAC80211 does
pass skb packets that are cloned. The assert is also not needed as
it does not lead to a failure state in our driver when the packet is
cloned. Therefore the assert can safely be removed.

0a0b7a5f7a can: add driver for Softing card
This patch adds the driver that creates a platform:softing device
from a pcmcia_device
Note: the Kconfig indicates a dependency on the softing.ko driver,
but this is purely to make configuration intuitive. This driver will
work independent, but no CAN network devices appear until softing.ko is
loaded too.

93789b32db x86, hotplug: Fix powersavings with offlined cores on AMD
ea53069231 made a CPU use monitor/mwait
when offline. This is not the optimal choice for AMD wrt to powersavings
and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the
same selection whether to use monitor/mwait has to be used as when we
select the idle routine for the machine.

With this patch, offlining cores 1-5 on a X6 machine allows core0 to
boost again.

[ hpa: putting this in urgent since it is a (power) regression fix ]

727a99a576 drivers: mmc: msm: remove clock disable in probe
The probe function adds the MMC host which can start accepting request
immediately. There is an assumption here that no requests happen
immediatly, but it's not always the case. This assumption can causes
a BUG() when the clocks are disabled. The fix is to just remove the
clock disable in the probe function.
