2010-05-19V4L/DVB: gspca - sn9c20x: HAS_BUTTON flag -> HAS_NO_BUTTON flagBrian Johnson
Reverse HAS_BUTTON logic since most webcams either have a button or if they don't don't bother to send any interrupts. However I have at least one model that appears to leave the button GPIO floating and can send a bogus interrupt.

2010-05-19V4L/DVB: usbvision: add delay before detecting the saa711xHans Verkuil

handle this v4l2_device_register already sets intfdata, no need to do this again. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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: v4l2-dev: remove unnecessary lock around atomic clear_bitHans Verkuil

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. Thanks to Mats Randgaard for bringing this to my attention. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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. These changes will simplify the work of moving priority handling into the v4l core. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Also removed the bogus zeroing of fmt.sliced when setting up raw VBI. Switching between raw and sliced VBI changed in 2.6.28 and this memset should have been removed at that time.

videobuf_pages_to_sg() and videobuf_vmalloc_to_sg() happen to create a scatterlist element for every page.

2010-05-19V4L/DVB: cx88: fix setting input when using DVBIstvan Varga
In cx88-mpeg.c, there is code that sets core->input to CX88_VMUX_DVB. However, this may be incorrect, since core->input is actually an index to core->board.input[], which has not enough elements to be indexed by the value of CX88_VMUX_DVB. So, the modified code searches core->board.input[] for an input with a type of CX88_VMUX_DVB, and if it does not find one, the index is simply set to zero. The change may not have much effect, though, since it appears the only case when core->input is actually used is when the current input is being queried.

Pulse-distance is not a protocol, it is a line coding (used by some protocols, like NEC).
