Subject: cfg80211: export reg_initiator_name()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=034c6d6e675f84ef5e67445150522b2517d963c9;p=openwrt%2Fstaging%2Fblogic.git

cfg80211: export reg_initiator_name()

Drivers can now use this to parse the regulatory request and
be more verbose when needed.
