From 0f836ca4c122f4ef096110d652a6326fe34e6961 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 31 Mar 2006 11:52:25 -0500 Subject: [PATCH] [PATCH] driver core: safely unbind drivers for devices not on a bus This patch (as667) changes the __device_release_driver() routine to prevent it from crashing when it runs across a device not on any bus. This seems logical, inasmuch as the corresponding bus_add_device() routine has an explicit check allowing it to accept such devices.
