From eeb89ab1f081a62bee1695d82442996b99a5b2b3 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 30 Jul 2013 20:10:46 +0200 Subject: [PATCH] iwlwifi: pcie: fix resume when no opmode is present If no opmode is present during suspend/resume (i.e. if the iwldvm or iwlmvm isn't loaded) the driver crashes during resume, trying to call the rfkill notification. Avoid that, and also don't enable the rfkill interrupt in this case (to avoid crashing trying to handle the interrupt later.)
