From: Stefan Richter Date: Tue, 20 Mar 2007 21:43:22 +0000 (+0100) Subject: ieee1394: fix oops on "modprobe -r ohci1394" after network class_device conversion X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7a9eeb2fa1b3a3a83670b9ba08dd396beedb88f8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ieee1394: fix oops on "modprobe -r ohci1394" after network class_device conversion The networking subsystem has been converted from class_device to device but ieee1394 hasn't. This results in a 100% reproducible NULL pointer dereference if the ohci1394 driver module is unloaded while the eth1394 module is still loaded. http://lkml.org/lkml/2006/11/16/147 http://lkml.org/lkml/2007/3/14/4 This is a regression in 2.6.21-rc1.
