Subject: [PATCH 2/3] ALSA: sgio2audio: Improve a size determination in snd_sgio2audio_create()
Date: Sat, 11 Nov 2017 20:22:36 +0100	[thread overview]
Message-ID: <f7ebb350-79c1-6ce2-eb15-bef62c631cb4@users.sourceforge.net> (raw)
In-Reply-To: <eb375101-03bd-37bb-67ef-e261eeca206e@users.sourceforge.net>

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.
