Subject: wl12xx: enable/disable role on interface add/remove
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b78b47eb73fcf4f04226ab8014aa8dadf11675d9;p=mv-sheeva.git

wl12xx: enable/disable role on interface add/remove

According to the new multi-role flow, we have to enable the
role before using (starting) it, and disable it on cleanup
(after it's no longer needed).
