Subject: [PATCH] ASoC: Intel: Fix incorrect sizeof() in sst_hsw_stream_get_volume()
Date: Sun, 13 Apr 2014 19:56:36 +0200	[thread overview]
Message-ID: <20140413195636.32f31cb2@spike> (raw)

[-- Attachment #1: Type: text/plain, Size: 911 bytes --]

Fix an incorrect sizeof() usage in sst_hsw_stream_get_volume(). sst_dsp_read()
is called to read into a variable of type u32, but is passed sizeof(u32 *) for
argument 'size_t bytes'. Detected by Coverity: CID 1195260.
