2008-01-11V4L/DVB (6999): ivtv: stick to udelay=10 after allHans Verkuil
Using an udelay of 5 seems to result in problems for several people. For now abandon the udelay value of 5 and stick to 10, even though this will mean a longer load time of the cx2584x firmware.

2007-10-23[PATCH] Fix breakage after SG cleanupsRalf Baechle
Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

2007-10-22V4L/DVB (6347): ivtv: fix video mute when radio is usedHans Verkuil

2007-10-22V4L/DVB (6346): ivtvfb: YUV output size fix when ivtvfb is not loadedIan Armstrong
If the ivtvfb module isn't loaded, the valid YUV output area should be set to full-screen. This patch fixes the case where the valid output area was not reset when the output broadcast format was changed from NTSC to PAL. This resulted in output being limited to the top 480 lines of the display.

2007-10-22V4L/DVB (6345): ivtvfb: YUV handling of an image which is not visible in the ↵Ian Armstrong
display area When the ivtvfb module is loaded, the YUV output is relative to the framebuffer output. When a virtual screen size is used, the output area for the YUV may actually be off screen. To prevent the hardware from crashing, the current driver will ignore an off-screen position and leave the output visible at the last on-screen position. This may not be desirable, so this patch will switch off the YUV output should the image move off-screen, and re-enable it should the image move on-screen again.

2007-10-22V4L/DVB (6342): ivtv: fix circular locking (bug 9037)Hans Verkuil
If you try to access the video device from within an udev rule, then you get into a circular locking situation.

2007-10-22V4L/DVB (6340): ivtvfb: screen mode change sometimes goes wrongIan Armstrong
This patch partially reverts a previous change that caused the CX2341X_OSD_SET_PIXEL_FORMAT firmware calls to be skipped when the pixel format of the framebuffer wasn't altered by FBIOPUT_VSCREENINFO. Unfortunately, another firmware call on the PVR350 sometimes scrambles the display when trying to adjust the framebuffer settings. This patch re-enables the CX2341X_OSD_SET_PIXEL_FORMAT calls to try and prevent this from occurring.

Also fixed a few cases of cut&paste errors where 'buf' would be set to the first entry in the list prior to be used as the loop iterator. In one case the value of buf was used before it was changed, but the rest were unnecessary. There was one list_for_each+list_entry loop that wasn't changed, since it depending on the loop iterator being left as NULL if the list was empty.

The driver should now pass the 'busy' state of the device to the cx2341x module whenever controls are set or tried. -EBUSY will be returned if the device is busy and the user attempts to modify certain 'dangerous' controls. It concerns controls that change the audio or video compression mode and bitrates. The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy) to the cx2341x, effectively keeping the old behavior for now.
