Subject: [PATCH AUTOSEL 5.8 09/24] net/fsl: quieten expected MDIO access failures
Date: Mon, 12 Oct 2020 15:02:24 -0400	[thread overview]
Message-ID: <20201012190239.3279198-9-sashal@kernel.org> (raw)
In-Reply-To: <20201012190239.3279198-1-sashal@kernel.org>

From: Jamie Iles <jamie@nuviainc.com>

[ Upstream commit 1ec8e74855588cecb2620b28b877c08f45765374 ]

MDIO reads can happen during PHY probing, and printing an error with
dev_err can result in a large number of error messages during device
probe.  On a platform with a serial console this can result in
excessively long boot times in a way that looks like an infinite loop
when multiple busses are present.  Since 0f183fd151c (net/fsl: enable
extended scanning in xgmac_mdio) we perform more scanning so there are
potentially more failures.

Reduce the logging level to dev_dbg which is consistent with the
Freescale enetc driver.
