Subject[PATCH 4.14 098/109] mac80211: remove BUG() when interface type is invalid
4.14-stable review patch.  If anyone has any objections, please let me know.


From: Luca Coelho <>

[ Upstream commit c7976f5272486e4ff406014c4b43e2fa3b70b052 ]

In the ieee80211_setup_sdata() we check if the interface type is valid
and, if not, call BUG(). This should never happen, but if there is
something wrong with the code, it will not be caught until the bug
happens when an interface is being set up. Calling BUG() is too
extreme for this and a WARN_ON() would be better used instead. Change
