Subject: rt2x00: Use ieee80211 fc handlers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac1044628d477d655f5f70420c3493119abeb6d3;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

rt2x00: Use ieee80211 fc handlers

With the introduction of the ieee80211 fc handlers
we can now remove the rt2x00.h versions to use the
global versions.
