Subject: [PATCH 2/3] i3c: Generate aliases for i3c modules
Date: Sat, 22 Feb 2020 11:27:10 +0100 [thread overview]
Message-ID: <20200222102711.1352006-3-boris.brezillon@collabora.com> (raw)
In-Reply-To: <20200222102711.1352006-1-boris.brezillon@collabora.com>
This part was missing, thus preventing user space from loading modules
automatically when MODALIAS uevents are received.
