From: Daniel Mack Date: Wed, 1 Aug 2012 05:08:47 +0000 (-0700) Subject: Input: rotary-encoder - defer calls gpio_to_irq() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a78769b80d73468d53d0ad70c5a9e3fd9ff9dc54;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Input: rotary-encoder - defer calls gpio_to_irq() Don't call gpio_to_irq() on GPIOs before gpio_request() succeeded on them. This avoids Ooopses with incorrect DT bindings.
