Subject: [PATCH 5/7] USB: serial: xr: add support for XR21B1411
Date: Fri, 26 Feb 2021 14:28:31 +0100 [thread overview]
Message-ID: <8acfa60a02c6f7473615fe4f53b3244579a1fa25.1614345081.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1614345081.git.mchehab+huawei@kernel.org>
There's nothing special on this device: it has just one port.
The only difference is that it uses a different register set.
