From: Rafał Miłecki Date: Thu, 1 Mar 2018 11:32:07 +0000 (+0100) Subject: mac80211: rename patches accepted upstream X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a186c2ab70d3980d3da502da7e08fb3644104815;p=librecmc%2Flibrecmc.git mac80211: rename patches accepted upstream This is to simplify maintenance. It's easy to say now which patches need some extra work and/or sending upstream. Updating to newer backports should be also simpler with this.
