Subject: [PATCH 4/5] USB: serial: kobil_sct: log failure to update line settings
Date: Wed,  1 Jul 2020 18:53:41 +0200	[thread overview]
Message-ID: <20200701165342.15448-5-johan@kernel.org> (raw)
In-Reply-To: <20200701165342.15448-1-johan@kernel.org>

Log failure to update the line settings in set_termios().

This also avoids a W=1 (-Wunused-but-set-variable) warning.
