Subject: [PATCH 3.16 030/346] ath9k: Fix programming of minCCA power threshold

3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Sven Eckelmann <sven@...fation.org>

commit aaab50fcea78ae3414c3afc25aae8d0603df34d0 upstream.

The function ar9003_hw_apply_minccapwr_thresh takes as second parameter not
a pointer to the channel but a boolean value describing whether the channel
is 2.4GHz or not. This broke (according to the origin commit) the ETSI
regulatory compliance on 5GHz channels.

Fixes: 3533bf6b15a0 ("ath9k: Fix regulatory compliance")
