Subject: sh: Allow GPIO chips to register IRQ mappings.
X-Git-Tag: v3.12-rc1~8388^2~39
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=532f3759d71d1fceb494212187dacc5a78295dc3;p=kernel%2Fkernel-generic.git

sh: Allow GPIO chips to register IRQ mappings.

As non-PFC chips are added that may support IRQs, pass through to the
generic helper instead of triggering the WARN_ON().
