Subject: [PATCH AUTOSEL 4.4 33/38] iwlwifi: trans: consider firmware dead after errors
Date: Tue, 22 Dec 2020 21:25:11 -0500	[thread overview]
Message-ID: <20201223022516.2794471-33-sashal@kernel.org> (raw)
In-Reply-To: <20201223022516.2794471-1-sashal@kernel.org>

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 152fdc0f698896708f9d7889a4ba4da6944b74f7 ]

If we get an error, no longer consider the firmware to be
in IWL_TRANS_FW_ALIVE state.
