Subject: [PATCH 2/3] i3c: Generate aliases for i3c modules
Date:   Sat, 22 Feb 2020 11:27:10 +0100
Message-Id: <20200222102711.1352006-3-boris.brezillon@collabora.com>

Precedence: bulk

This part was missing, thus preventing user space from loading modules
automatically when MODALIAS uevents are received.
