[PATCH 2/4] ARM: OMAP: Improve a size determination in two functions

From: SF Markus Elfring

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.

This issue was detected by using the Coccinelle software.
