[patch 069/108] ath9k: Fix bug in determining calibration support

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

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

From: Sujith <Sujith.Manoharan@xxxxxxxxxxx>

commit a451aa66dcb14efcb7addf1d8edcac8df76a97b6 upstream.

ADC gain calibration has to be done for all non 2GHZ-HT20 channels.
Regression from "ath9k: use ieee80211_conf on ath9k_hw_iscal_supported()"
