Please submit patches using subject lines reflecting the style for the subsystem, this makes it easier for people to identify relevant patches. Look at what existing commits in the area you're changing are doing and make sure your subject lines visually resemble what they're doing. There's no need to resubmit to fix this alone.

The mtk_memif_set_addr() and mtk_memif_set_format() functions always returns 0, so it is necessary to remove the check of its return value (which was probably specified by analogy with the check of return values for other functions) to make the code more readable Found by Linux Verification Center (linuxtesting.org) with SVACE.
