* V4L/DVB (9166): ivtv - Fix potential race condition in yuv handlerIan Armstrong2008-10-13
| | | | | | | | | | | | | Modified yuv register update handling to remove a potential race condition which could occur with the first video frame. Also removed a forced yuv position update, since changing the source video dimensions or interlace settings doesn't affect the frame already being displayed.

* V4L/DVB (9162): ivtv: fix raw/sliced VBI mixupHans Verkuil2008-10-13
| | | | | | | | | | | | | | The service_set field was used in saa7115 and cx25840 to determine whether raw or sliced VBI was desired. This is incorrect since it is perfectly valid to select sliced VBI with a service_set of 0. Instead these drivers should checked on VIDIOC_S_FMT whether the type field matches the raw or sliced VBI type. Updated ivtv accordingly.

* V4L/DVB (9133): v4l: disconnect kernel number from minorHans Verkuil2008-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | The v4l core creates four different video devices (video, vbi, radio, vtx) and each has its own range of minor numbers. However, modern devices keep increasing the number of devices that they need so a maximum of 64 video devices will not be enough in the future. In addition this scheme makes it very hard to add new device types. This patch disconnects the kernel number allocation (e.g. video0, video1, etc.) from the actual minor number (just pick the first free minor). This allows for much more flexibility in the future. However, it does require the use of udev. For those who cannot use udev a new CONFIG option was created that changes the allocation scheme back to the old behavior. Thanks to Greg KH for suggesting this approach during the 2008 LPC. In addition, several bugs were fixed in the ivtv and cx18 drivers: these drivers try to allocate specific kernel numbers but that scheme contained a bug which caused what should have been e.g. video17 to appear as e.g. video2.
