Subject: [PATCH AUTOSEL 4.4 094/174] spi: spi-fsl-spi: call spi_finalize_current_message() at the end
Date: Thu, 16 Jan 2020 12:41:31 -0500 [thread overview]
Message-ID: <20200116174251.24326-94-sashal@kernel.org> (raw)
In-Reply-To: <20200116174251.24326-1-sashal@kernel.org>
From: Christophe Leroy <christophe.leroy@c-s.fr>
[ Upstream commit 44a042182cb1e9f7916e015c836967bf638b33c4 ]
spi_finalize_current_message() shall be called once all
actions are finished, otherwise the last actions might
step over a newly started transfer.
Fixes: c592becbe704 ("spi: fsl-(e)spi: migrate to generic master queueing")
