From fc46e1b2a24a0c85e8469576f66f9a991411bfc7 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Thu, 10 Dec 2020 16:05:19 +0200 Subject: [PATCH] ath11k: mhi: print a warning if firmware crashed There was no way to detect if the firmware crashed so add a warning. At the moment the firmware is not restarted or anything like that, so when this happens ath11k modules need to be reloaded.
