Subject: [PATCH 2/3] mtdswap: Improve two size determinations in mtdswap_add_mtd()
Date: Mon, 8 May 2017 17:09:04 +0200	[thread overview]
Message-ID: <cfc8598b-9552-9321-9fad-497415c1b0ee@users.sourceforge.net> (raw)
In-Reply-To: <82e905b5-3958-be81-b0ee-d0a2805154df@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 8 May 2017 16:18:49 +0200

Replace the specification of two 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.
