From 65bec836da8394b1d56bdec2c478dcac21cf12a4 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 8 Jun 2021 11:32:29 +0200 Subject: cfg80211: shut down interfaces on failed resume If resume fails, we should shut down all interfaces as the hardware is probably dead. This was/is already done now in mac80211, but we need to change that due to locking issues, so move it here and do it without the wiphy lock held.
