[PATCH 4.9 030/102] mac80211: ibss: Fix channel type enum in ieee80211_sta_join_ibss()

From: Greg Kroah-Hartman
Date: Fri Apr 06 2018 - 10:36:03 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Matthias Kaehlcke <mka@xxxxxxxxxxxx>

commit a4ac6f2e53e568a77a2eb3710efd99ca08634c0a upstream.

cfg80211_chandef_create() expects an 'enum nl80211_channel_type' as
channel type however in ieee80211_sta_join_ibss()
NL80211_CHAN_WIDTH_20_NOHT is passed in two occasions, which is of
the enum type 'nl80211_chan_width'. Change the value to NL80211_CHAN_NO_HT
(20 MHz, non-HT channel) of the channel type enum.
