From 4eaf317a60fbea0555b936035002ca9bd9b9105d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Winiarski?= Date: Thu, 12 Jul 2018 17:53:30 +0200 Subject: [PATCH] drm/i915/kvmgt: Fix compilation error MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit gvt_pin_guest_page extracted some of the gvt_dma_map_page functionality: commit 79e542f5af79 ("drm/i915/kvmgt: Support setting dma map for huge pages") And yet, part of it was reintroduced in: commit 39b4cbadb9a9 ("drm/i915/kvmgt: Check the pfn got from vfio_pin_pages") Causing kvmgt part to no longer build. Let's remove it.
