Subject: [PATCH 2/4] axonram: Improve a size determination in axon_ram_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 3 Aug 2017 20:00:16 +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.
