From 7ee69102dbc4eea90f46a24f16961226a477dd4c Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 9 Jan 2018 17:09:17 +0100 Subject: serdev: only match serdev devices Only serdev devices (a.k.a. clients or slaves) are bound to drivers so bail out early from match() in case the device is not a serdev device (i.e. if it's a serdev controller).
