Subject: [PATCH 3/4] GPU-DRM-QXL: Improve a size determination in
 qxl_driver_load()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 21 Sep 2016 22:48:34 +0200

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
