From: Markus Elfring <elfring@users.sourceforge.net> Date: Sun, 14 Jan 2018 21:19:10 +0100
Replace the specification of two 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.
