From 590dfe2f3bbbbeee806ee91bef68ba2a6afc16d2 Mon Sep 17 00:00:00 2001 From: Michal Kubecek Date: Wed, 25 Jan 2012 16:51:05 +0100 Subject: agp: fix scratch page cleanup In error cleanup of agp_backend_initialize() and in agp_backend_cleanup(), agp_destroy_page() is passed virtual address of the scratch page. This leads to a kernel warning if the initialization fails (or upon regular cleanup) as pointer to struct page should be passed instead.
