The mt9t031 driver hasn't yet been updated to support asynchronous subdevice probing. If such a probing is attempted, the driver is allowed to fail, but it shouldn't Oops. This patch fixes such a potential NULL pointer dereference. Signed-off-by:

The soc-camera core does all the work on supporting asynchronous subdevice probing, host drivers only have to pass a subdevice list to soc-camera. Typically this list is provided by the platform. Signed-off-by:

With synchronous subdevice probing regulators should be requested by the soc-camera core in soc_camera_pdrv_probe(). Subdevice drivers, supporting asynchronous probing, call soc_camera_power_init() to request regulators. Erroneously, the same regulator array is used in the latter case as in the former, which leads to a failure. This patch fixes it by preventing the second regulator request from being executed.

Add Renesas R-Car VIN (Video In) V4L2 driver. Based on the patch by Phil Edworthy <phil.edworthy@renesas.com>. [Sergei: removed deprecated IRQF_DISABLED flag, reordered/renamed 'enum chip_id' values, reordered rcar_vin_id_table[] entries, removed senseless parens from to_buf_list() macro, used ALIGN() macro in rcar_vin_setup(), added {} to the *if* statement and used 'bool' values instead of 0/1 where necessary, removed unused macros, done some reformatting and clarified some comments.] Signed-off-by:Vladimir Barinov <vladimir.barinov@cogentembedded.com> Signed-off-by:

changeset 2ccf12af did a crappy job when added multi-line comment lines, violating CodingStyle.

Use the new blanking and frame size defines. This also fixed a bug in these drivers: they assumed that the height for interlaced formats was the field height, however height is the frame height. So the height for a field is actually bt->height / 2. Signed-off-by:

v4l2-common.c contained a bunch of dv-timings related functions. Move that to the new v4l2-dv-timings.c which is a more appropriate place for them. There aren't many drivers that do HDTV, so it is a good idea to separate common code related to that into a module of its own. Signed-off-by:

I did some tests against modulator (television signal generator) and this seems to improve sensitivity a little bit on channel I used. Used device was able to receive transmission just as weak signal as with Windows XP. Thanks to Jacek for donating his non-working device. I cannot ask he to test anymore... Reported-by:

Each source entity maintains a pointer to the counterpart sink entity while an enabled link connects them. It should be managed by the setup_link callback in the media controller framework at runtime. However, enabled links which connect RPFs and WPFs that have an equivalent index number are created during initialization. This registers the pointer to a sink entity from the source entity when an enabled link is created. Signed-off-by:

The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage. Signed-off-by:

The vb2_fop_mmap() and vb2_fop_get_unmapped_area() functions are plug-in implementation of the mmap() and get_unmapped_area() file operations that calls vb2_mmap() and vb2_get_unmapped_area() on the queue associated with the video device. Neither the vb2_fop_mmap/vb2_fop_get_unmapped_area nor the v4l2_mmap/vb2_get_unmapped_area functions in the V4L2 core take any lock, leading to race conditions between mmap/get_unmapped_area and other buffer-related ioctls such as VIDIOC_REQBUFS. Fix it by taking the queue or device lock around the vb2_mmap() and vb2_get_unmapped_area() calls. Signed-off-by:
