The slock spinlock in the cx23885_dev struct is only initialised if analogue video is being used, but is used in other places too, leading to the attached lockdep complaint. Move the lock initialisation so that it is done unconditionally. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

JPEG codecs on Exynos4 and Exynos3250 SoCs utilize different number of planes for storing the raw image data, depending on the format of the image being processed. For the unused planes a random data was being written to the related registers. Regardless of the fact that this seemed not to be harmful, fix the issue for clarity reasons. Reported-by:

Xilinx platforms have no hardwired video capture or video processing interface. Users create capture and memory to memory processing pipelines in the FPGA fabric to suit their particular needs, by instantiating video IP cores from a large library. The Xilinx Video IP core is a framework that models a video pipeline described in the device tree and expose the pipeline to userspace through the media controller and V4L2 APIs. Signed-off-by:

While running v4l2-compliance tests on vivid I suddenly got errors due to a call to vmalloc_user with size 0 from vb2. Digging deeper into the cause I discovered that this was due to the fact that struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32. The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32 bit pixelformat. So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And bytesperline * height is suddenly 0 as well. While the vivid driver may be a virtual driver, it is to be expected that this limit will be hit for real hardware as well in the near future: 8k deep-color video will already reach it. The solution is to change the type to __u32. The only drivers besides vivid that use the multiplanar API are little-endian ARM and SH platforms (exynos, ti-vpe, vsp1), so this is safe. Signed-off-by:
