Subject: [PATCH RFC/RFT] regulator: Fix mask parameter in da9052_reg_update
 calls

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
