Tim Schmielau 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).

Arjan van de Ven 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.

Mauro Carvalho Chehab e75f9cee32 V4L/DVB (4861): Remove the need of a STD array for drivers using video_ioctl2
video_ioctl2 will auto-generate standard entries at ENUM_FMT.
Also, now, a driver may return a subset of the video array at
the return, to be stored as the current_norm.
For example, a driver may ask for V4L2_STD_PAL. At return,
driver may change it to V4L2_STD_PAL_B. This way, a futher call
to G_STD will return the exact detected video std.

Jonathan Corbet 83427ac5d6 V4L/DVB (4743): Fix oops in VIDIOC_G_PARM
The call to v4l2_std_construct() in the VIDIOC_G_PARM handler treats
vfd->current_norm as if it were an index - but it's not.  The result is
an oops if the driver has no vidioc_g_parm() method defined.  Here's the
fix.

Jonathan Corbet b7de567bf3 [PATCH] VIDIOC_ENUMSTD bug
The v4l2 API documentation for VIDIOC_ENUMSTD says:

	To enumerate all standards applications shall begin at index
	zero, incrementing by one until the driver returns EINVAL.

The actual code, however, tests the index this way:

               if (index<=0 || index >= vfd->tvnormsize) {
                        ret=-EINVAL;

So any application which passes in index=0 gets EINVAL right off the bat
- and, in fact, this is what happens to mplayer.  So I think the
following patch is called for, and maybe even appropriate for a 2.6.18.x
stable release.

Add proper error checking and roll-back for failure of
class_device_create_file() in videodev.c.  Print error messages and
unroll partially created sysfs entries.
Also, failure of class_device_register() in video_register_device() is
handled correctly.  It was failing to de-allocate the minor number.  This
must be done in video_register_device(), since the caller has no way of
knowing if failure occurred before or after the class device was
registered.
Also added an error message if video_register_device() is called with
an unknown type, which should never happen.

Michael Krufky 3117beec7e V4L/DVB (4316): Check __must_check warnings
Check __must_check warnings for class_device_register and class_device_create_file

video_device_create_file was declared as a void, but instead should
return the int value of class_device_create_file.

Move the check from bttv-driver.c into v4l2-dev.h, because all other
callers of video_device_create_file must also be checked.

Replace the call to class_device_create_file in videodev.c with
video_device_create_file, as defined in v4l2-dev.h, so that the
return value of class_device_create_file will be checked.

Check the return value of class_device_register in videodev.c and
pvrusb2-sysfs.c
