[110/244] ath9k_hw: fix calibration on 5 ghz
From: Greg KH
Date: Wed Sep 28 2011 - 18:43:01 EST
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Felix Fietkau <nbd@xxxxxxxxxxx>
commit 0e4660cbe51276e86dbdab17228733dbcdb49249 upstream.
ADC calibrations cannot run on 5 GHz with fast clock enabled. They
need to be disabled, otherwise they'll hang and IQ mismatch calibration
will not be run either.
