de6a1b8edc V4L/DVB (5032): Improves some USBVision info messages
Replaces the info statements with printk(KERN_INFO statements.
This will cut down on the useless information which is showing up
 in the kernel messages log file.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

12a917f69d i2c: Declare more i2c_adapter parent devices
Declare the parent device of i2c_adapter devices each time we can
easily do so. It makes the i2c_adapter appear at the right place in
the device tree, rather than as a platform device.

fa027c2a0a [PATCH] mark struct file_operations const 4
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

c430ca1e16 V4L/DVB (5019): Fix the frame->grabstate update in read() entry point.
The Coverity checker spotted that in usbvision_v4l2_read(), the variable
"frmx" is never assigned any value different from -1, but it's used an 
an array index in "usbvision->frame[frmx]".

  Additional check in order to return 0 if the driver is not opened.
- Whitespace cleanups in usbvision-cards.c

This patch merges two fixes by Thierry MERLE and Mauro Chehab, and adds
additional checks.
