Merge branch 'fix-smsc911x-regulator' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Browse Source 
From Tony Lindgren:

"Here's one more kernel panic fix that I dropped from last weeks
fixes as it was still being discussed.

This is a fix for the regression caused by fixing an earlier
regression for smsc911x fixed regulators :(

Turns out that we have more than one smsc911x on some boards,
and the earlier fix causes a kernel panic for board trying to
register second smsc911x instance, even if the second smsc911x
is on an add-on board that is not connected.

Note that the boards with second smsc911x will also need to be
patched later on to provide their own regulators."
