From c2873e9633fe908dccd36dbb1d370e9c59a1ca62 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Thu, 7 Oct 2010 09:20:12 +0100 Subject: [PATCH] drm/i915: Free hardware status page on unload when physically mapped A physically mapped hardware status page is allocated at driver load time but was never freed. Call the existing code to free this page at driver unload time on hardware which uses this kind.
