Subject: [PATCH 4.4 25/28] USB: cdc-acm: downgrade message to debug
Date: Mon, 5 Apr 2021 10:53:59 +0200 [thread overview]
Message-ID: <20210405085017.815311945@linuxfoundation.org> (raw)
In-Reply-To: <20210405085017.012074144@linuxfoundation.org>
From: Oliver Neukum <oneukum@suse.com>
commit e4c77070ad45fc940af1d7fb1e637c349e848951 upstream.
This failure is so common that logging an error here amounts
to spamming log files.
