I assume you see some breakage without your patch?  In mainline?

This is not true in mainline, until 060d20d (imx/gpio: Use
handle_level_irq) (currently in imx/mxc-master) hits Linus' tree ...

... so there is no hurry.

Can you please test with 060d20d if your breakage still occurs and
if it is still valid report some details (for me and the commit log)?

Best regards
