Use sizeof instead of ARRAY_SIZE to fix this smatch warning: drivers/media/usb/em28xx/em28xx-i2c.c:952 em28xx_do_i2c_scan() warn: calling memset(x, y, ARRAY_SIZE()); Do the same for the em28xx_hash_mem() call in the same function. smatch didn't pick that up, but there too it should use sizeof instead of ARRAY_SIZE.

Instead of validating the links to capture devices and subdevices with the same function, use the default v4l function for links between subdevices and only use a different function for validating between capture device and subdevice. This change should also ease future work to associate multiple mbus codes for the same pixelformat in vimc_pix_map.

The kernel driver never touches the decoded buffers with the CPU. All accesses are either done by hardware DMA masters or userspace mapping the buffers. This means we don't need a kernel virtual address mapping for those buffers at all. As those buffers are usually quite large, we can save a good deal of kernel vmalloc space by requesting to not have a kernel mapping set up for them. Signed-off-by:

The BIT decoder picture run temporarily locks the bitstream mutex while the coda device mutex is locked, to refill the bitstream ring buffer. Consequently, the decoder start command, which locks both mutexes when flushing the bitstream ring buffer, must lock the coda device mutex first as well, to avoid an ABBA deadlock.

Allwinner H3 SoC contains deinterlace unit, which has several modes of operation - bypass, weave, bob and mixed (advanced) mode. I don't know how mixed mode works, but according to Allwinner it gives best results, so they use it exclusively. Currently this mode is also hardcoded here. For each interleaved frame queued, this driver produces 2 deinterlaced frames. Deinterlaced frames are based on 2 consequtive output buffers, except for the first 2, where same output buffer is given to peripheral as current and previous. There is no documentation for this core, so register layout and fixed values were taken from BSP driver. I'm not sure if maximum size of the image unit is capable to process is governed by size of "flag" buffers, frequency or it really is some HW limitation. Currently driver can process full HD image in ~15ms (7.5ms for each capture buffer), which allows to process 1920x1080@60i video smoothly in real time. Acked-by:
