Subject: [PATCH 3.2 137/200] ath9k: Fix ETSI compliance for AR9462 2.0

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

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

From: Sujith Manoharan <c_manoha@....qualcomm.com>

commit b3050248c167871ca52cfdb2ce78aa2460249346 upstream.

The minimum CCA power threshold values have to be adjusted
for existing cards to be in compliance with new regulations.
Newer cards will make use of the values obtained from EEPROM,
support for this was added earlier. To make sure that cards
that are already in use and don't have proper values in EEPROM,
do not violate regulations, use the initvals instead.
