From 8f5dcb1cfb71ce832f53a4723deba72e6695078b Mon Sep 17 00:00:00 2001 From: Vasanthakumar Thiagarajan Date: Fri, 26 Nov 2010 06:10:06 -0800 Subject: [PATCH] ath9k: Reintroduce modparam to enable btcoex It is not ideal to enable btcoex based on subsys id as it is not unique, they are so random. It is also a pain keeping all of them in a table to enable btcoex for a particular hw. Going back to the old idea. Signed-off-by: Vasanthakumar Thiagarajan Signed-off-by: John W.
