cppcheck incorrectly produces an error here: [drivers/media/platform/vicodec/vicodec-core.c:1677]: (error) Pointer addition with NULL pointer. While this is actually a false positive, it doesn't hurt to reorder the checks to make the code simpler, handling first the error patch, where no color or alpha components are there.
