Subject: [PATCH AUTOSEL 6.1 05/35] firmware: arm_scmi: Clear stale xfer->hdr.status
Date: Tue, 24 Jan 2023 08:41:01 -0500 [thread overview]
Message-ID: <20230124134131.637036-5-sashal@kernel.org> (raw)
In-Reply-To: <20230124134131.637036-1-sashal@kernel.org>
From: Cristian Marussi <cristian.marussi@arm.com>
[ Upstream commit f6ca5059dc0d6608dc46070f48e396d611f240d6 ]
Stale error status reported from a previous message transaction must be
cleared before starting a new transaction to avoid being confusingly
reported in the following SCMI message dump traces.
