Subject: [PATCH 08/14] USB: legousbtower: remove tower_abort_transfers()
Date: Tue,  5 Nov 2019 09:41:46 +0100	[thread overview]
Message-ID: <20191105084152.16322-9-johan@kernel.org> (raw)
In-Reply-To: <20191105084152.16322-1-johan@kernel.org>

Drop the tower_abort_transfers() function which is now only called from
release and instead explicitly kill the two URBs.

This incidentally also fixes the outdated comment about freeing memory.
