From 228670b2e6f8d32f11d27c5165fb42a2c77f062c Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Sun, 10 Aug 2014 17:00:15 +0300 Subject: [PATCH] iwlwifi: mvm: clear d0i3 state on recovery If recovery happened after mvm entered d0i3 (e.g. due to sysassert when releasing the bus), the mvm->state wasn't cleared properly, causing the ongoing recovery to fail (due to iwl_mvm_ref_sync failure). This in turn fails the ongoing recovery, and triggers a reprobe, which terminates any ongoing wifi activity.
