The purpose of this patch is to split off the case when a device does
not reply on the lower level (which is reported by HC hardware), and
a case when the device accepted the request, but does not reply at
upper level. This redefinition allows to diagnose issues easier,
without asking the user if the -110 happened "immediately".The usbmon splits such cases already thanks to its timestamp, but
it's not always available.I adjusted all drivers which I found affected (by searching for "urb").
Out of tree drivers may suffer a little bit, but I do not expect much
breakage. At worst they may print a few messages.Signed-off-by: Pete Zaitcev

i2c-algo-bit: Discard the mdelay data struct member
The i2c_algo_bit_data structure has an mdelay member, which is not
used by the algorithm code (the code has always been ifdef'd out.)
Let's discard it to save some code and memory.Signed-off-by: Jean Delvare

Small driver suspend() fixes in preparation for the PRETHAW events:
- Only compare message events for equality against PM_EVENT_* codes;
not against integers, or using greater/less-than comparisons.
(PM_EVENT_* should really become a __bitwise thing.)- Explicitly test for SUSPEND events (rather than not-something-else)
before suspending devices.- Removes more of the confusion between a pm_message_t (wraps event code)
and a "state" ... suspend() originally took a target system state.These updates are correct and appropriate even without new PM_EVENT codes.

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= 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.Signed-off-by: Jonathan Corbet

V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined,
to allow checking for broken V4L2 ports. This is very important during the
migration phase for V4L2 API.
However, userspace apps should be capable of using both APIs, since they need
to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when
__KERNEL__ is not defined, those ioctls and corresponding structs should be
visible.
This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that
where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT
and CONFIG_VIDEO_V4L2.Signed-off-by: Mauro Carvalho Chehab

"I can enable Logitech quickcam support in .config, but it want be compile.
I have to add into drivers/media/video/Makefile:

A previous patch changed VBI_OFFSET to match what the datasheets say it
should be. However, the bt8x8 datasheets are wrong. The old value of
244 is closer to what is actually observed. The real value appears to
not be constant and is different for different chip revisions.

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.Signed-off-by: Trent Piepho
