Subject: [PATCH] ARM: orion5x: Fix GPIO enable bits for MPP9
Date: Sat, 07 Apr 2012 05:08:45 +0100 [thread overview]
Message-ID: <1333771725.7150.32.camel@deadeye> (raw)
Commit 554cdaefd1cf7bb54b209c4e68c7cec87ce442a9 seems to have
accidentally inverted the GPIO valid bits for MPP9 (only). For the
mv2120 platform which uses MPP9 as a GPIO LED device, this results in
the error:
[ 12.711476] leds-gpio: probe of leds-gpio failed with error -22

I know nothing about this platform, and this is totally untested. But
it does look quite straightforward...
Ben.
