From be860f4e4dc4dfc8b3f473f0e5640bbd4d2d783e Mon Sep 17 00:00:00 2001 From: Gaetan Rivet Date: Sat, 15 Jul 2017 19:56:40 +0200 Subject: [PATCH] bus/pci: fix generic driver pointer on probe error The field is set but never resetted on error. This marks the device as being attached while it is not, and forbid further attempts to hotplug it.
