[PATCH 23.05 2/2] mac80211: backport ieee80211_set_sband_iftype_data()

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

It's needed by some drivers, e.g. mt7925, see:
mt7925/main.c:264:9: error: implicit declaration of function '_ieee80211_set_sband_iftype_data' [-Werror=implicit-function-declaration]
