[PATCH v3 06/18] wcn36xx: Add helper macros to cast sta to priv

From: Bjorn Andersson
Date: Tue Apr 19 2016 - 01:06:52 EST


From: Pontus Fuchs <pontus.fuchs@xxxxxxxxx>

While poking at this I also change two related things. I rename one
variable to make the names consistent. I also move one assignment of
priv_sta to the declaration to save a few lines.
