Subject: [PATCH 3/7] USB: cdc-acm: drop redundant driver-data assignment
Date: Thu, 18 Mar 2021 16:51:58 +0100	[thread overview]
Message-ID: <20210318155202.22230-4-johan@kernel.org> (raw)
In-Reply-To: <20210318155202.22230-1-johan@kernel.org>

The interface driver data has already been set by
usb_driver_claim_interface() so drop the redundant subsequent
assignment.
