[PATCH] ioremap balanced with iounmap for drivers/video/ffb
ioremap must be balanced by an iounmap and failing to do so can result in a memory leak. Signed-off-by: Amol Lad <amol@verismonetworks.com> Cc: "Antonino A. Daplas" <adaplas@pol.net> Cc: David S. Miller <davem@davemloft.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
