[ 04/53] ARM: orion5x: Fix GPIO enable bits for MPP9

From: Ben Hutchings
Date: Thu May 17 2012 - 23:11:02 EST


3.2.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

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
