2007-10-17backport commit 7eff2e7a8b65c25920207324e56611150eb1cd9aMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Original Description: Author: Kay Sievers <kay.sievers@vrfy.org> Date: Tue Aug 14 15:15:12 2007 +0200 Driver core: change add_uevent_var to use a struct This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-10-14ivtv: fix video mute when radio is usedHans Verkuil

2007-10-14ivtvfb: YUV output size fix when ivtvfb is not loaded.Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> 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. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-10-14ivtvfb: YUV handling of an image which is not visible in the display area.Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> 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.

From: Hans Verkuil <hverkuil@xs4all.nl> If you try to access the video device from within an udev rule, then you get into a circular locking situation. Changed the driver to postpone the registration of the devices until everything else has been fully initialized, so that the newly created device can be used immediately.

2007-10-12ivtvfb: screen mode change sometimes goes wrong.Hans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> 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.

2007-10-12 Additional Fixes for saa7134 suspend/resumeMauro Carvalho Chehab
From: Maxim Levitsky <maximlevitsky@gmail.com> Fixes few more problems I found in my saa7134 resume code: * Race between IRQ handler and .suspend()/.resume() functions * Removes timeout timers on active buffers - those buffers will be recaptured after resume * Adds suspend/resume for IR code - probably necessary if using polling mode * Adds #ifdef CONFIG_PM overs suspend code * Runs a quirk in set_tvnorm in suspend/resume too * Rearranges the order of calls in saa7134_resume to be exactly as in saa7134_initdev thus the card is initialized in exactly the same way * Since DMA audio capture suspend/resume isn't yet supported, avoid re-enabling it on resume for now Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

From: Florin Malita <fmalita@gmail.com> Both cx23885_initdev and cx23885_dev_setup free the device in their error path so a failure in the latter causes a double-free. Since cx23885_dev_setup is only called from cx23885_initdev, it should be safe to remove its deallocation and leave the cleanup up to the allocating function. Coverity CID 1922.

From: Mauro Carvalho Chehab <mchehab@infradead.org> struct video_device used to define a .hardware field. While initialized on severl drivers, this field is never used inside V4L.
