| Subject: USB: g_printer: fix bug in unregistration |
| |
| From: Fabian Godehardt <fg@emlix.com> |
| |
| commit 8582d86143c690c68cc42f996def466a035bee34 upstream. |
| |
| 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. |
