Subject: [PATCH AUTOSEL 5.10 21/25] ata: pata_arasan_cf: Use dev_err_probe() instead dev_err() in data_xfer()
Date: Sun, 13 Aug 2023 12:09:32 -0400 [thread overview]
Message-ID: <20230813160936.1082758-21-sashal@kernel.org> (raw)
In-Reply-To: <20230813160936.1082758-1-sashal@kernel.org>
From: Minjie Du <duminjie@vivo.com>
[ Upstream commit 4139f992c49356391fb086c0c8ce51f66c26d623 ]
It is possible for dma_request_chan() to return EPROBE_DEFER, which
means acdev->host->dev is not ready yet. At this point dev_err() will
have no output. Use dev_err_probe() instead.
