Merge branch 'akpm' (patches from Andrew Morton)
Merge leftovers from Andrew Morton:
"A few leftovers: ocfs2, gcov, RTC"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
rtc: s5m: consolidate two device type switch statements
rtc: s5m: add support for S2MPS14 RTC
rtc: s5m: support different register layout
rtc: s5m: use shorter time of register update
rtc: s5m: remove undocumented time init on first boot
mfd/rtc: sec/s5m: rename SEC* symbols to S5M
gcov: add support for GCC 4.9
ocfs2/o2net: incorrect to terminate accepting connections loop upon rejecting an invalid one
