From 6136f97cd2dd2b5a88d62bd73cc663a803124c09 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 21 Jun 2018 19:27:17 -0700 Subject: HID: i2c-hid: Add vddl regulator control Some wacom w9013 devices have a vddl supply for "low valtage" requirements. Add support in this driver to turn on this low voltage supply. We can also drop a handful of error messages because the regulator core is already printing an error when bulk regulators fail to enable or disable.
