Bjorn mentioned me on IRC that this is because of a missing commit in my

daa6e41ce2b5 soc: qcom: wcnss_ctrl: Stub wcnss_ctrl API

When I pull the tag below (which contains the above commit) wcn36xx
builds fine for me:


Andy, is it ok if I pull your tag also to my ath.git tree to solve the
wcn36xx build problem? My trees go to Linus via net-next and I don't
know when exactly Dave would send a pull request to Linus, before or
after the arm trees, but as the tag seems to contain only few patches I
hope it doesn't matter.
