From: Pontus Fuchs Date: Tue, 19 Apr 2016 05:00:44 +0000 (-0700) Subject: wcn36xx: Add helper macros to cast sta to priv X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a92e4696292199714d47d8e52c4bf0318324f77f;p=deliverable%2Flinux.git wcn36xx: Add helper macros to cast sta to priv 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.
