Subject: [PATCH 2/5] cris: nand: Improve a size determination in crisv32_nand_flash_probe()
Date: Wed, 4 Oct 2017 20:46:15 +0200	[thread overview]
Message-ID: <c2a6e5a5-0120-d16f-d809-8d5a67fba413@users.sourceforge.net> (raw)
In-Reply-To: <cd84411c-d202-70d6-dec2-c02bedaf3594@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 4 Oct 2017 18:00:33 +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.
