Subject: gpio/omap: (re)fix wakeups on level-triggered GPIOs
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b3c64bc30af67ed328a8d919e41160942b870451;p=openwrt%2Fstaging%2Fblogic.git

gpio/omap: (re)fix wakeups on level-triggered GPIOs

commit 1b1287032 (gpio/omap: fix missing check in *_runtime_suspend())
broke wakeups on level-triggered GPIOs by adding the enabled
non-wakeup GPIO check before the workaround that enables wakeups
on level-triggered IRQs, effectively disabling that workaround.

To fix, move the enabled non-wakeup GPIO check after the
level-triggered IRQ workaround.
