From 478573c93abd369c4850de55c387be43aa01e2e8 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Thu, 28 Jul 2016 02:25:41 +0200 Subject: [PATCH] driver core: Don't leak secondary fwnode on device removal If device_add_property_set() is called for a device, a secondary fwnode is allocated and assigned to the device but currently not freed once the device is removed. This can be triggered on Apple Macs if a Thunderbolt device is plugged in on boot since Apple's NHI EFI driver sets a number of properties for that device which are leaked on unplug.
