Subject: [PATCH 03/10] dlm: Improve a size determination in table_seq_start()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 6 May 2017 08:34:27 +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.
