From aa8e2435b3d4878a0db8917805e86f61001fe174 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Thu, 7 Feb 2019 09:59:28 +0100 Subject: [PATCH] drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same value. The only exception is vboxvideo, which is being converted to the new offset by this patch. Unifying the constants in a single place simplifies the driver code.
