Subject: [PATCH 5/7] EDAC/amd64: Improve two size determinations in
 probe_one_instance()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 25 Dec 2023 17:24:37 +0100

Replace the specification of 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.
