[PATCH 2/3] soc-knav_dma: Improve a size determination in knav_dma_probe()

[elfring@users.sourceforge.net (SF Markus Elfring)]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 1 May 2017 21:06:46 +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.
