Subject: Re: [PATCH V2 1/2] brcm80211: use container_of to resolve brcms_phy from brcms_phy_pub

From: "John W. Linville" <[email-masked]>
Date: Fri, 26 Sep 2014 13:46:37 -0400

These two patches don't seem to apply on wireless-next, and I don't
have time at the moment to fix them up.  Feel free to repost...
