Gah, I even had the NULL checks in there once. commit 5472359d6860af655a3c286d30558540376c9fdb Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Oct 8 15:23:13 2010 +0100 dri: Check for pixmap privates before dereferencing them It is still possible for the pixmap allocator to return a software only pixmap (i.e. without an associated GEM buffer or intel_pixmap), so check before dereferencing. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=30707 Reported-by: Matthias Hopf <mhopf@suse.de> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Wow, that was quick! Thanks, Chris I don't promise that is the last one. ;-) |
