From 8582d86143c690c68cc42f996def466a035bee34 Mon Sep 17 00:00:00 2001 From: Fabian Godehardt Date: Thu, 1 Sep 2011 14:15:46 +0200 Subject: [PATCH] USB: g_printer: fix bug in unregistration The allocated chardevice region range is only 1 device but on unregister it currently tries to deregister 2. Found this while doing a insmod/rmmod/insmod/rm... of the module which seemed to eat major numbers.
