mmc: fix the use of kunmap_atomic() in tmio_mmc.h
commit 5600efb1bc2745d93ae0bc08130117a84f2b9d69 upstream. kunmap_atomic() takes the cookie, returned by the kmap_atomic() as its argument and not the page address, used as an argument to kmap_atomic(). This patch fixes the compile error: In file included from drivers/mmc/host/tmio_mmc.c:37: drivers/mmc/host/tmio_mmc.h: In function 'tmio_mmc_kunmap_atomic': drivers/mmc/host/tmio_mmc.h:192: error: negative width in bit-field '<anonymous>' Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Eric Miao <eric.y.miao@gmail.com> Tested-by: Magnus Damm <damm@opensource.se> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
