Use NULL when calling a function with pointer parameter, initializing a pointer and returning a pointer. This will remove the following sparse warning at different locations (see "make C=1"): * warning: Using plain integer as NULL pointer Signed-off-by:

When power management is not configured (CONFIG_PM) then some code is no longer necessary. This patch will remove the following compiler warnings: * pd-dvb.c: In function 'poseidon_fe_release': * pd-dvb.c:101: warning: unused variable 'pd' * pd-video.c:14: warning: 'pm_video_suspend' declared 'static' but never defined * pd-video.c:15: warning: 'pm_video_resume' declared 'static' but never defined Signed-off-by:

When temporarily there is no video signal, sometimes it takes more than 0.5 secs for the cx88 chip to generate a single frame. If a dma timeout occurs during recording, it confuses the recording application (at least mencoder) and the recording stops. Since there is already an #if 0 for 2 seconds buffer timeout in the code at the -hg development tree, re-enabling that seemed the most simple solution. Signed-off-by:

Address a problem found in MythTV where if we are in digital mode, switch to analog mode, and the switch back to digital mode, the first tuning request after switching back to digital mode gets dropped. This is because the au8522 maintains internal state, and would think the demod was already tuned to the target frequency. Thanks to Zaphod Beeblebrox for reporting this issue. Signed-off-by:

With applications like MythTV, switching inputs results in closing the digital side and then immediately opening the analog side. This exposes a race condition where the dvb_frontend kernel thread powers down the chip and closes the i2c gate even though we're in the middle of bringing up the analog part of the chip (since the shutdown of the dvb_frontend kernel thread occurs asychronously). Introduce a construct to keep track of what mode we're in, and drop requests to power down or management the gate if we've already switched to analog mode. Thanks to Zaphod Beeblebrox for reporting this issue. Signed-off-by:

If the platform hooks are provided, soc_camera powers off the device on close and powers it on on open. This resets the ADDRESS_MODE registers which then can be different to the value the driver has computed for them. This patch setups runtime pm usage for mt9t031 and uses the resume function to write the ADDRESS_MODE registers in order to fix the above described problem. Signed-off-by:

To save power soc-camera powers subdevices down, when they are not in use, if this is supported by the platform. However, the V4L standard dictates, that video nodes shall preserve configuration between uses. This requires runtime power management, which is implemented by this patch. It allows subdevice drivers to specify their runtime power-management methods, by assigning a type to the video device. Signed-off-by:

V4L/DVB: The first two parameters of soc_camera_limit_side() are usually pointers to struct v4l2_rect elements. They are signed, so adjust the prototype accordingly This will remove the following sparse warning (see "make C=1"): * incorrect type in argument 1 (different signedness) expected unsigned int *start got signed int *<noident> as well as a couple more signedness mismatches.

Test the just-allocated value for NULL rather than some other value. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,y; statement S; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ( if ((x) == NULL) S | if ( - y + x == NULL) S ) // </smpl> Signed-off-by:

Fix a regression in the firmware loading time where it went from 1080 ms to 4700 ms. This was noticed when the em28xx based HVR-950 took noticably longer to load the driver. Regression introduced in hg 12824. The developer added an msleep() call with an argument based on a newly introduced xc3028_ctrl field, which is left initialized to zero for pretty much every board that is currently supported.
