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. > You should make sure that > the fix for your problem is not causing new problems for other 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? -- Regards, Shawn
