Merge tag 'omap-for-v3.9/fixes-non-critical-signed-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical
From Tony Lindgren:
Few fixes for v3.9 merge window that are not urgent for
the -rc series.
* tag 'omap-for-v3.9/fixes-non-critical-signed-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: using strlcpy instead of strncpy
ARM: OMAP2+: Fix selection of clockevent timer when using device-tree
ARM: OMAP: Fix the use of uninitialized dma_lch_count
ARM: OMAP: make wakeupgen_lock raw
+ Linux 3.8-rc6
