From 44a7102484db0ddfa6f855b57ffe0566f739b55a Mon Sep 17 00:00:00 2001 From: Matthew Auld Date: Tue, 12 Apr 2016 16:57:42 +0100 Subject: [PATCH] drm/i915: call kunmap_px on pt_vaddr We need to kunmap pt_vaddr and not pt itself, otherwise we end up mapping a bunch of pages without ever unmapping them.
