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

From: SF Markus Elfring

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.
