[PATCH 4.4 51/70] UAS: no use logging any details in case of ENODEV

From: Greg Kroah-Hartman
Date: Fri May 01 2020 - 09:26:38 EST


From: Oliver Neukum <oneukum@xxxxxxxx>

commit 5963dec98dc52d52476390485f07a29c30c6a582 upstream.

Once a device is gone, the internal state does not matter anymore.
There is no need to spam the logs.
