[PATCH 3.12 049/133] ath9k: Disable cross-band FCC

From: Greg Kroah-Hartman
Date: Tue Feb 04 2014 - 17:21:38 EST

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


From: Sujith Manoharan <c_manoha@xxxxxxxxxxxxxxxx>

commit 1e2f9295f4c657500111514f92a3d3894d0e05b4 upstream.

Fast Channel Change across bands was enabled for
AR9462 recently, but this is causing baseband issues.
Disable it until this feature is tested well. Also,
remove the feature bit for AR9565 since it is
a single-band card and doesn't support this feature.
