Subject: ath9k: move bt_stomp_type to driver core
X-Git-Tag: v2.6.33-rc1~388^2~865^2~129
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e08a6ace7db089dc111c6d0abe9278226c39b7b0;p=karo-tx-linux.git

ath9k: move bt_stomp_type to driver core

The bt_stomp_type defines the bt coex weight, it has a one-to-one
mapping. In the future we may want to just use the weight directly.
