Subject: [PATCH RFC/RFT] regulator: Fix mask parameter in da9052_reg_update calls
Date: Fri, 02 Mar 2012 18:07:21 +0800	[thread overview]
Message-ID: <1330682841.4191.1.camel@phoenix> (raw)

If the mask parameter is 0, info->activate_bit bit won't be set by
calling da9052_reg_update.

Hi,
I cannot find the datasheet, but current code looks does not make sense.
Can someone confirm if this is a correct fix?

Regards,
Axel
