Subject: ARM: orion5x: Fix GPIO enable bits for MPP9
From: Ben Hutchings <[email protected]>
commit 48d99f47a81a66bdd61a348c7fe8df5a7afdf5f3 upstream.
Commit 554cdaefd1cf7bb54b209c4e68c7cec87ce442a9 ('ARM: orion5x: Refactor
mpp code to use common orion platform mpp.') 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
