From 751e7489c1d74b94ffffbed619d8fd724eeff4ee Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 7 Oct 2024 15:00:58 +0300 Subject: wifi: mac80211: expose ieee80211_chan_width_to_rx_bw() to drivers Drivers might need to also do this calculation, no point in them duplicating the code. Since it's so simple, just make it an inline.
