[PATCH] drivers/rtc/rtc-mrst.c: Use release_mem_region after request_mem_region

[Julia Lawall]

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>
