There are several coding style issues at those definitions, and the previous patchset added even more. Address the trivial ones by first calling: ./scripts/checkpatch.pl --strict --fix-inline include/media/v4l2-async.h include/media/v4l2-fwnode.h include/media/v4l2-mediabus.h drivers/media/v4l2-core/v4l2-async.c drivers/media/v4l2-core/v4l2-fwnode.c and then manually adjusting the style where needed.
