[PATCH 1/5] atm: Improve a size determination in four functions

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sun, 21 May 2017 21:20:44 +0200

Replace the specification of four 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.
