Subject: [PATCH 2/3] char/bsr: Improve a size determination in bsr_add_node()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 15 Oct 2017 21:25:46 +0200

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