Subject: ath9k: replaces SC_OP_BTCOEX_ENABLED with a bool
X-Git-Tag: v2.6.33-rc1~388^2~865^2~130
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8c1b39547e2562f9aa0cc00b1a7d4cc325a46a4c;p=karo-tx-linux.git

ath9k: replaces SC_OP_BTCOEX_ENABLED with a bool

Whether or not bluetooth coex has been enabled is a hardware
state and only the hardware helpers will be able to set this.
