Subject: gpio/nomadik: use genirq core to track enablement
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=479a0c7eee68243ad9915a9ccc217a35c4e5e0e2;p=linux-beck.git

gpio/nomadik: use genirq core to track enablement

Currently the Nomadik GPIO driver tracks enabled/disabled interrupt
status with a local variable, switch to using the interrupt core.
