Subject: [PATCH v2 3/4] i3c: Generate aliases for i3c modules
Date: Thu, 27 Feb 2020 12:31:08 +0100 [thread overview]
Message-ID: <79687073b915182e06fccfb18adcedfd0fadbc99.1582796652.git.vitor.soares@synopsys.com> (raw)
In-Reply-To: <cover.1582796652.git.vitor.soares@synopsys.com>
In-Reply-To: <cover.1582796652.git.vitor.soares@synopsys.com>
From: Boris Brezillon <boris.brezillon@collabora.com>
This part was missing, thus preventing user space from loading modules
automatically when MODALIAS uevents are received.
