A slightly different version of this is already in linux-next as commit
bb60424af517d6e6148505fb5ef256caa91b5b43.
It was in your 'fixes' branch, and was merged by Olaf from Tony on 3/13:
Merge branch 'fix-smsc911x-regulator' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
