drivers/rtc/rtc-mrst.c: use release_mem_region after request_mem_region
The memory allocated using request_mem_region should be released using release_mem_region, not release_region. The semantic patch that fixes part of this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1,E2,E3; @@ request_mem_region(E1,E2,E3) ... ?- release_region(E1,E2) + release_mem_region(E1,E2) // </smpl> [akpm@linux-foundation.org: use resource_size()] Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
