Subject[PATCH 2/3] jffs2: Improve a size determination in jffs2_scan_medium()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 18 Aug 2017 20:22:15 +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.

This issue was detected by using the Coccinelle software.
