Subject: [PATCH AUTOSEL 4.14 19/23] pktcdvd: remove warning on attempting to register non-passthrough dev
Date: Sun, 29 Sep 2019 13:35:29 -0400	[thread overview]
Message-ID: <20190929173535.9744-19-sashal@kernel.org> (raw)

[ Upstream commit eb09b3cc464d2c3bbde9a6648603c8d599ea8582 ]

Anatoly reports that he gets the below warning when booting -git on
a sparc64 box on debian unstable:

Apparently debian auto-attaches any cdrom like device to pktcdvd, which
can lead to the above warning. There's really no reason to warn for this
situation, kill it.
