From bd8f8e7b2bcedcbba32f8b0c49f02c8a97f5d308 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Tue, 20 Aug 2024 13:29:32 -0700 Subject: [PATCH] soc: qcom: pmic_glink: Actually communicate when remote goes down commit ad51126037a43c05f5f4af5eb262734e3e88ca59 upstream. When the pmic_glink state is UP and we either receive a protection- domain (PD) notification indicating that the PD is going down, or that the whole remoteproc is going down, it's expected that the pmic_glink client instances are notified that their function has gone DOWN. This is not what the code does, which results in the client state either not updating, or being wrong in many cases. So let's fix the conditions.
