Subject: [PATCH 2/2] ASoC: cs35l32: Improve two size determinations in cs35l32_i2c_probe()
Date: Wed, 22 Nov 2017 20:58:28 +0100	[thread overview]
Message-ID: <521550ca-c13e-e647-5bbe-d8b172a6445b@users.sourceforge.net> (raw)
In-Reply-To: <caf22f25-6c27-b869-89e8-ef2904a2baf2@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 22 Nov 2017 20:40:47 +0100

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.

This issue was detected by using the Coccinelle software.
