ps3av: misc updates
ps3av: - Move the definition of struct ps3av to ps3av.c, as it's locally used only. - Kill ps3av.sem, use the existing ps3av.mutex instead. - Make the 512-byte buffer in ps3av_do_pkt() static to reduce stack usage. Its use is protected by a semaphore anyway. Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
