Subject: [PATCH 3/5] ATM-nicstar: Improve another size determination in
 ns_init_card()

From: Markus Elfring <elfring@...rs.sourceforge.net>

Replace the specification of a data structure by a reference for a field
in a local variable as the parameter for the operator "sizeof" to make
the corresponding size determination a bit safer according to
the Linux coding style convention.
