Subject: [PATCH AUTOSEL 6.1 41/47] ata: pata_arasan_cf: Use dev_err_probe() instead dev_err() in data_xfer()
From: Minjie Du <duminjie@...o.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.
