Bjorn mentioned me on IRC that this is because of a missing commit in my tree: 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: git://git.kernel.org/pub/scm/linux/kernel/git/agross/linux.git tags/qcom-drivers-for-4.10 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. -- Kalle Valo
