From d68475de9637a476ad8e5870060ccc69a80f2299 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Wed, 22 Feb 2012 12:40:49 +0530 Subject: [PATCH] ath9k: Initialize BTCOEX scheme using a helper Setting up the required scheme can be done as part of the BTCOEX initialization path and it doesn't belong in ath9k_hw_fill_cap_info() anyway.
