Subject: [patch] ASoC: Intel: some incorrect sizeof() usages
Date: Wed, 16 Apr 2014 15:38:11 +0000 [thread overview]
Message-ID: <20140416153811.GB16325@mwanda> (raw)
In-Reply-To: <20140413195636.32f31cb2@spike>
The intent was to say "sizeof(*pos)" and not "sizeof(pos)".
The sizeof(*pos) is 8 bytes so the bug won't show up on 64 bit systems.
The sizeof(*dx) is 172 bytes so that will be a bugfix.
