From a5d0f5766f2e9cb04f0f775bf679d41ae1a54d50 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 3 Jun 2013 16:10:41 +0300 Subject: [PATCH] drm/vmwgfx: Don't access file_priv in cursor_set when handle==0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We want to disable the cursor by calling ->cursor_set() with handle=0 from places where we don't have a file_priv, so don't try to access it unless necessary.
