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

From: SF Markus Elfring
Date: Mon May 01 2017 - 15:32:41 EST


From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

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.
