It's exactly the reason why you chose to fix the problem in gpio-mxc
instead of gpio-generic, right?  You thought other gpio-generic users
like gpio-mxs does not suffer from this problem.  Sadly, it's not the
case.

The updated patch simply corrects behaviour of gpio-generic for all
the users.

I'm not fixing a gpio-mxs problem but a gpio-generic one.  Can you help
me understand what the new problems could possibly be introduced for
other gpio-generic users by the changes?
