Merge tag 'omap-cleanup-a2-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into cleanup-sparse
Resolve static analysis warnings generated by files in
arch/arm/mach-omap1, arch/arm/mach-omap2, and arch/arm/plat-omap.
Fixes all but one sparse warning and most of the useful
cppcheck warnings (excepting the warnings generated by the
dmtimer integration code which is going up via 3.4-rc fixes)
