From 829d5f68ec59ff7c0fdd472132680df8e4b64f3e Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 28 Mar 2006 01:56:18 -0800 Subject: [PATCH] [PATCH] paride-pt: register_chrdev fix If the user specified `major=0' (odd thing to do), pt.c will use dynamic allocation. We need to pick up that major for subsequent unregister_chrdev().
