From 5bfadc8255e2cd92be7538fd7dfa777c27f58be0 Mon Sep 17 00:00:00 2001 From: Haim Dreyfuss Date: Mon, 12 Sep 2016 10:24:19 +0300 Subject: [PATCH] iwlwifi: mvm: comply with fw_restart mod param on suspend If the suspend flow fails, we restart the hardware to go back to the D0 image (with non-unified images), but we don't comply with the fw_restart module parameter. If something goes wrong when starting the D3 image, we may want to debug it, so we should comply with the fw_restart flag to avoid clearing everything up and losing the firmware state when the error occurred.
