Subject: [PATCH 03/25] thunderbolt: Log error if adding switch fails
Date: Wed, 23 Oct 2019 14:21:32 +0300 [thread overview]
Message-ID: <20191023112154.64235-4-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20191023112154.64235-1-mika.westerberg@linux.intel.com>
If we fail to add a switch for some reason log an error instead of
keeping silent. This is useful for debugging.
