[PATCH 05/14] GPU-DRM-OMAP: Improve a size determination in dmm_txn_append()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 21 Sep 2016 13:53:11 +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.
