Subject: [PATCH v3 3/3] USB: serial: blacklist USB-UIRT when driver is selected
Date: Thu,  6 May 2021 13:44:55 +0100	[thread overview]
Message-ID: <37339f4102666345168a738d0ffd80d8133a6a03.1620304986.git.sean@mess.org> (raw)
In-Reply-To: <cover.1620304986.git.sean@mess.org>

The USB-UIRT device has its own driver, so blacklist the fdti driver
from using it if the driver has been enabled.
