openwrt/package/kernel/mac80211/patches/rt2x00/050-rt2x00-add-RT3883-support.patch
Daniel Golle 26dafeeba4 mac80211: rt2x00: replace patches with upstream version 
Support for RT3883/RT3663 was merged upstream [1]. Use that patch
instead of our original series. The resulting source tree is
exactly identical, this commit is merely reorganizing the patches.
