[PATCH] lindent rio drivers
Run all rio files through indent -kr -i8 -bri0 -l255, as requested by Alan. rioboot.c and rioinit.c were skipped due to worrisome lindent warnings. Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
