Moving the pxa_camera driver from soc_camera lots the implied VIDEO_V4L2 Kconfig dependency, and building the driver without V4L2 results in a kernel that cannot link: drivers/media/platform/pxa_camera.o: In function `pxa_camera_remove': pxa_camera.c:(.text.pxa_camera_remove+0x10): undefined reference to `v4l2_clk_unregister' pxa_camera.c:(.text.pxa_camera_remove+0x18): undefined reference to `v4l2_device_unregister' drivers/media/platform/pxa_camera.o: In function `pxa_camera_probe': pxa_camera.c:(.text.pxa_camera_probe+0x458): undefined reference to `v4l2_of_parse_endpoint' drivers/media/v4l2-core/videobuf2-core.o: In function `__enqueue_in_driver': drivers/media/v4l2-core/videobuf2-core.o: In function `vb2_core_streamon': videobuf2-core.c:(.text.vb2_core_streamon+0x1b4): undefined reference to `v4l_vb2q_enable_media_source' drivers/media/v4l2-core/videobuf2-v4l2.o: In function `vb2_ioctl_reqbufs': videobuf2-v4l2.c:(.text.vb2_ioctl_reqbufs+0xc): undefined reference to `video_devdata' This adds back an explicit dependency.

There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). While we are at it, we do a small optimization with the reinitialization of the completion before we use it. The usage pattern of the completion is: waiter context waker context send_packet() reinit_completion() usb_sumbit_urb() wait_for_completion_interruptible() usb_tx_callback() complete() imon_disconnect() complete() Signed-off-by:Daniel Wagner <daniel.wagner@bmw-carit.de> Signed-off-by:

Documentation states that the "default-input" property should reside directly in the node of the device. This adjusts the parsing to make the implementation consistent with the documentation. Based on patch by William Towle <william.towle@codethink.co.uk>. Signed-off-by:

The text states that default-input is an endpoint property, but in the example it is a device property. The default input is a property of the chip, not of a particular port, so the example makes more sense. Signed-off-by:

The advertised V4L2 pixel format and Media Bus code don't match. The current media bud code advertised is MEDIA_BUS_FMT_YUYV8_2X8 which does not reflect what the encoder actually outputs. This encoder generate MEDIA_BUS_FMT_UYVY8_2X8 so advertise as such. Signed-off-by:

Function ite_set_carrier_params() uses variable use_demodulator after having initialized it to false in some if branches, but this variable is never set to true otherwise.

In mb86a20s_read_status_and_stats(), when mb86a20s_read_status() fails, the function returns the value in variable rc without initializing it first. Fix this by propagating the error code from variable status_nr. This bug has been found using clang and -Wsometimes-uninitialized warning flag. Signed-off-by:

Some devices have invalid baSourceID references, causing uvc_scan_chain() to fail, but if we just take the entities we can find and put them together in the most sensible chain we can think of, turns out they do work anyway. Note: This heuristic assumes there is a single chain. At the time of writing, devices known to have such a broken chain are - Acer Integrated Camera (5986:055a) - Realtek rtl157a7 (0bda:57a7) Signed-off-by:

These formats store the color information of the image in a geometrical representation. The colors are mapped into a cylinder, where the angle is the HUE, the height is the VALUE and the distance to the center is the SATURATION. This is a very useful format for image segmentation algorithms. Signed-off-by:

Don't complain about a failure to compute the pre_pll divisor. The function is used to determine whether a particular combination of bits per sample value and a link frequency can be used, in which case there are lots of unnecessary driver messages. During normal operation the failure generally does not happen. Use dev_dbg() instead. Signed-off-by:
