Subject: [PATCH RESEND net-next] cfg80211: remove unused callback
Date:   Sat,  6 Feb 2021 20:47:47 +0100

From: Matteo Croce <mcroce@microsoft.com>

The ieee80211 class registers a callback which actually does nothing.
Given that the callback is optional, and all its accesses are protected
by a NULL check, remove it entirely.
