Tony Lindgren 3c101c41fb 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:
