If an error happens in jpeg_get_drv_data(), i.e. match fails, jpeg->variant field is NULL, so we cannot access it. Consider device probe failed if jpeg->variant is NULL. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

VP8 in Cedrus shares same engine as H264. Note that it seems necessary to call bitstream parsing functions, to parse frame header, otherwise decoded image is garbage. This is contrary to what is driver supposed to do. However, values are not really used, so this might be acceptable. It's possible that bitstream parsing functions set some internal VPU state, which is later necessary for proper decoding. Biggest suspect is "VP8 probs update" trigger. Signed-off-by:

On AMD Family 15h (Models 30h-3fh), I/O Memory Management Unit RiSC engine sometimes stalls, requiring a reset. As result, MythTV and w-scan won't scan channels on the AMD Kaveri APU with the Hauppauge QuadHD TV tuner card. For the solution I added the Input/Output Memory Management Unit's PCI Identity of 0x1423 to the broken_dev_id[] array, which is used by a quirks logic meant to fix similar problems with other AMD chipsets.

To comply with the intended usage of the V4L2 selection target when used to retrieve a sensor image properties, adjust the rectangles returned by the imx219 driver. The top/left crop coordinates of the TGT_CROP rectangle were set to (0, 0) instead of (8, 8) which is the offset from the larger physical pixel array rectangle. This was also a mismatch with the default values crop rectangle value, so this is corrected. Found with v4l2-compliance. While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and CROP_BOUNDS have the same size as the non-active pixels are not readable using the selection API. Found with v4l2-compliance. [reword commit message, use macros for pixel offsets] Fixes: e6d4ef7d ("media: i2c: imx219: Implement get_selection") Signed-off-by:

The subdev's video device node was only assigned after registering the device node in the system. While it is unlikely that a driver needed to use this field in handling system calls to its file handle, there remains a slim chance the devnode field remains NULL while the driver expects to find a video node there. Assign the devnode field before registering the device, and assign it back to NULL if the registration failed. Signed-off-by:

The DT bindings documented "reset-gpios" property but the driver never made use of it. Instead it used a GPIO called "xshutdown", with apprently wrong polarity. Fix this by requesting "reset" GPIO with the right polarity first, and if that fails, then request "xshutdown" GPIO with the old polarity. This way it works for new users as expected while if someone, somewhere, depended on "xshutdown" GPIO, that continues to work as well. Signed-off-by:
