2013-02-05[media] s5p-fimc: Avoid null pointer dereference in fimc_capture_ctrls_create()Sylwester Nawrocki
With presence of some faults, e.g. caused by wrong platform data or the device tree structure the IDX_SENSOR entry in the array may be NULL, so make sure it is not dereferenced then.

2013-02-05[media] s5p-fimc: Change platform subdevs registration methodSylwester Nawrocki
The previous method of registering platform entities into the main driver using driver_find() and then iterating over devices bound to a driver was racy and is being removed here. Nothing was preventing module from unloading during a call to try_module_get(driver->owner). Instead, we look up a device first and then check for its driver while holding device lock. The platform sub-devices are looked up and registered to the top level driver. When any sub-device is not yet initialized and ready the main driver's probe() will be deferred.

2013-02-05[media] s5p-fimc: fimc-lite: Prevent deadlock at STREAMON/OFF ioctlsSylwester Nawrocki
This patch fixes regression introduced in commit 6319d6a002beb26631 '[media] fimc-lite: Add ISP FIFO output support'. In case of a configuration where video is captured at the video node exposed by the FIMC-LITE driver there is a following video pipeline: sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node In this situation s_stream() handler of the FIMC-LITE.n is called back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video node, through vb2_stream_on/off(), start/stop_streaming and fimc_pipeline_call(set_stream). The fimc->lock mutex is already held then, before invoking vidioc_streamon/off. So it must not be taken again in the s_stream() callback in this case, to avoid a deadlock. This patch makes fimc->out_path atomic_t so the mutex don't need to be taken in the FIMC-LITE subdev s_stream() callback in the DMA output case.

2013-02-05[media] tuner-core: map audmode to STEREO for radio devicesHans Verkuil
Fixes a v4l2-compliance error: setting audmode to a value other than mono or stereo for a radio device should map to MODE_STEREO. The spec specifies that for radio devices only mono and stereo audmodes are valid. If the user specifies another audmode in v4l2_tuner, then that should be mapped to valid audmode. That didn't happen here. Note that tuner drivers might decide to limit the possible audmode even further if it only supports mono. In that case the tuner driver can set audmode to mono. However, that new value wasn't copied back to t->audmode, and that has been fixed as well in this patch.

This patch adds a helper function that allows to modify range, i.e. minimum, maximum, step and default value of a v4l2 control, after the control has been created and initialized. This is helpful in situations when range of a control depends on user configurable parameters, e.g. camera sensor absolute exposure time depending on an output image resolution and frame rate. v4l2_ctrl_modify_range() function allows to modify range of an INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.

2013-02-05[media] omap3isp: preview: Lower the crop marginsLaurent Pinchart
The preview engine includes filters that consume columns and lines as part of their operation, thus resulting in a cropped image. To allow turning those filters on/off during streaming without affecting the output image size, the driver adds additional cropping to make the total number of cropped columns and lines constant regardless of which filters are enabled. This process needlessly includes the CFA filter, as whether the filter is enabled only depends on the sink pad format, which can't change during streaming. Exclude the CFA filter from the preview engine margins.
