If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From c329061be51bef655f28c9296093984c977aff85 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I <kishon@xxxxxx> Date: Mon, 27 Jul 2015 16:54:10 +0530 Subject: regulator: pbias: Fix broken pbias disable functionality From: Kishon Vijay Abraham I <kishon@xxxxxx> commit c329061be51bef655f28c9296093984c977aff85 upstream. regulator_disable of pbias always writes '0' to the enable_reg. However actual disable value of pbias regulator is not always '0'. Fix it by populating the disable_val in pbias_reg_info for the various platforms and assign it to the disable_val of pbias regulator descriptor. This will be used by regulator_disable_regmap while disabling pbias regulator.
