From 7f34778e79048fae1a88100de917277375466de0 Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Tue, 4 Sep 2012 19:33:38 +0530 Subject: [PATCH] ath9k_htc: Add a modparam to enable BTCOEX rather than default Enable BTCOEX for WB193(which seems to be the only supported ath9k_htc BTCOEX chipset)only when it is enabled via modparam, rather than enabling it by default.
