[PATCH] serial: merge mpsc.h into mpsc.c
Merge mpsc.h into mpsc.c because its the only file that #include's mpsc.h. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
