Subject: [PATCH] ASoC: Fix setting update bits for WM8741_DACRMSB_ATTENUATION
Date: Mon, 03 Oct 2011 11:09:01 +0800	[thread overview]
Message-ID: <1317611341.5065.1.camel@phoenix> (raw)

After checking the code and datasheet, I think what we want in the second
snd_soc_update_bits call is to update WM8741_DACRMSB_ATTENUATION register
instead of WM8741_DACRLSB_ATTENUATION.

I don't have this hardware handy, thus I only check the the code and datasheet.
The bug is there since commit 992bee40 "ASoC: Initial WM8741 CODEC driver".
I'd appreciate if someone can test this patch.

Regards,
Axel
