2010-06-01V4L/DVB: gspca - sonixb: Have 0c45:602e handled by sonixb instead of sn9c102Jean-François Moine

2010-06-01V4L/DVB: pvrusb2: Fix kernel oops on device tear-downMike Isely
pvrusb2: Delete sysfs class device as the _very_ last step, after we're sure that all driver contexts have gone away first. This is important because it appears that there isn't any protection from a struct device instance reference a deleted struct class instance. The assumption in the kernel code appears to be that the class instance is assumed to be around for the life of the device. So we can't let the class instance go away until all referencing device instances are gone; this is ensured by delaying removal of the class instance until after the driver contexts have all gone away. This bug has been present for a very long time but it didn't apparently become malignant until recently (probably because of other changes in the kernel).

2010-06-01V4L/DVB: pvrusb2: Fix minor internal array allocationMike Isely
pvrusb2: Need one extra attribute slot allocated so that worst case still has a trailing null pointer. This wasn't causing visible symptoms; it was found through inspection while investigating other issues.

2010-06-01V4L/DVB: pvrusb2: Fix USB parent device reference countMike Isely
pvrusb2: Correctly reference count pointer to parent USB device when linked from sysfs interface. This is technically a pretty nasty problem, however as far as I know nobody had been getting burned by it (yet).

2010-06-01V4L/DVB: pvrusb2: Fix kernel oops at device unregistrationMike Isely
pvrusb2: Fix oops caused by touching deleted memory after unregistration. This bug was introduced when we had started using video_device_node_name() - that function was being called potentially after the underlying structure (referenced by that function) had been deleted. The fix rearranges things slightly so that the function is called before destruction takes place. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-06-01V4L/DVB: pvrusb2: New feature to mark specific hardware support as experimentalMike Isely
This adds a flag in the device attribute structure which can be used to mark support for a particular device as experimental. Any devices flagged in this way, when encountered at run-time, will generate a warning message to the kernel log.

2010-05-19V4L/DVB: s2255drv: remove dead codeDan Carpenter
My concern initially was we dereference "dev" in the parameter list to s2255_dev_err() but it turns out that code path is never used. The s2255_stop_readpipe() is only called from one place and "dev" is never null. So this patch just removes the whole condition here.

2010-05-19V4L/DVB: hdpvr: fix disconnect sequenceHans Verkuil
Disconnecting the HDPVR caused a kernel oops if lockdep was enabled. In addition, if an app still had video0 open and attempted to call ioctl when the device was already disconnected the system would crash. Move the freeing and cleanup code to the release function: that is the right place for it since you know when you get there that nobody is using the device. Also removed usb_set_intfdata: v4l2_device_register sets this already to v4l2_dev. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-05-19V4L/DVB: tvp7002: fix query_dv_presetHans Verkuil
If no signal or valid format is detected, then VIDIOC_QUERY_DV_PRESET must return 0 and set the preset to V4L2_DV_INVALID. This driver returned an error instead. Also simplified the kernel messages a bit: change v4l2_err to v4l2_dbg (not detecting a signal/valid format is not an error, so only print this info when debug == 1) and do not call v4l_fill_dv_preset_info: it's overkill to do this just for a debug message.

2010-05-19V4L/DVB: v4l2-common: simplify prio utility functionsHans Verkuil
v4l2_prio_init/open/close returned an int when in fact they would always return 0. Make these void functions. v4l2_prio_close and v4l2_prio_check pass an enum v4l2_priority as a pointer for no good reason. Replace with a normal enum v4l2_priority argument.
