From e17e0ceb83538c015a50b965547f2f4d38f81c5d Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Mon, 24 Dec 2018 16:37:41 +0530 Subject: [PATCH] power: regulator: Return success on attempt to disable an always-on regulator commit 4f86a724e82c0 ("power: regulator: denied disable on always-on regulator") throws an error when requested to disable an always-on regulator. It is right that an always-on regulator should not be attempted to be disabled. But at the same time regulator framework should not return an error when such request is received. Instead it should just return success without attempting to disable the specified regulator. This is because the requesting driver will not have the idea if the regulator is always-on or not. The requesting driver will always try to enable/disable regulator as per the required flow. So it is upto regulator framework to not break such scenarios.
