Subject: [PATCH 11/12] USB: serial: ftdi_sio: simplify divisor handling
Date: Sun, 11 Sep 2022 16:02:15 +0200 [thread overview]
Message-ID: <20220911140216.30481-12-johan@kernel.org> (raw)
In-Reply-To: <20220911140216.30481-1-johan@kernel.org>
In preparation for adding further Hi-Speed types, assume the device type
is Hi-Speed unless it's an explicitly listed legacy type when
determining divisors.
