commit 22be8233b34f4f468934c5fefcbe6151766fb8f2 upstream.
The V4L2_PIX_FMT_BGRA444 define clashed with the pre-existing V4L2_PIX_FMT_SGRBG12 which strangely enough used the same fourcc, even though that fourcc made no sense for a Bayer format. In any case, you can't have duplicates, so change the fourcc of V4L2_PIX_FMT_BGRA444.
