Merge tag 'omap-cleanup-b-for-3.7' into test_v3.6-rc6_ocb3.7_cff3.7_odaf3.7

smatch and string-wrapping cleanups for the OMAP subarch code.

These changes fix some of the more meaningful warnings that smatch
returns for the OMAP subarch code, and unwraps strings that are
wrapped at the 80-column boundary, to conform with the current
practice.

Basic build, boot, and PM logs are available here:
