Subject: [PATCH v2 1/6] USB: Export generic USB device driver functions
Date: Tue, 15 Oct 2019 16:31:27 +0200	[thread overview]
Message-ID: <20191015143132.8099-2-hadess@hadess.net> (raw)
In-Reply-To: <20191015143132.8099-1-hadess@hadess.net>

This will make it possible to implement device drivers which extend the
generic driver without needing to reimplement it.
