Subject: ath9k: Initialize BTCOEX scheme using a helper
X-Git-Tag: v3.4-rc1~177^2~108^2~272
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d68475de9637a476ad8e5870060ccc69a80f2299;p=platform%2Fkernel%2Flinux-3.10.git

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.
