Subject: [PATCH 5.4 14/38] USB: serial: ftdi_sio: fix 300 bps rate for SIO
Date: Thu, 13 Oct 2022 19:52:15 +0200 [thread overview]
Message-ID: <20221013175144.747770047@linuxfoundation.org> (raw)
In-Reply-To: <20221013175144.245431424@linuxfoundation.org>
From: Johan Hovold <johan@kernel.org>
commit 7bd7ad3c310cd6766f170927381eea0aa6f46c69 upstream.
The 300 bps rate of SIO devices has been mapped to 9600 bps since
2003... Let's fix the regression.
