Subject: drivers/rtc/rtc-mrst.c: use release_mem_region after request_mem_region
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c258f9a0aab09366070f3c9283070edead23d4cf;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

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:

  request_mem_region(E1,E2,E3)
  ...
  ?- release_region(E1,E2)
  + release_mem_region(E1,E2)
  // </smpl>
