From 3a22ebe9cc76acac2511b1d3979a35609924ce42 Mon Sep 17 00:00:00 2001 From: Stefan Achatz Date: Sat, 29 Jan 2011 02:17:30 +0100 Subject: [PATCH] HID: hidraw: fix hidraw_disconnect() hidraw_disconnect() first sets an entry in hidraw_table to NULL and calls device_destroy() afterwards. The thereby called hidraw_release() tries to read this already cleared value resulting in never removing any device from the list. This got fixed by changing the order of events.
