[PATCH 2/5] mtip32xx: Improve a size determination in two functions

From: SF Markus Elfring
Date: Sun Aug 06 2017 - 15:20:37 EST

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