From d9b2c33c110863ea23e4f8b0e532cd42baad9986 Mon Sep 17 00:00:00 2001 From: Maulik Shah Date: Mon, 22 Jun 2020 12:23:25 +0530 Subject: [PATCH] soc: qcom: rpmh-rsc: Set suppress_bind_attrs flag rpmh-rsc driver is fairly core to system and should not be removable once its probed. However it allows to unbind driver from sysfs using below command which results into a crash on sc7180. echo 18200000.rsc > /sys/bus/platform/drivers/rpmh/unbind Lets prevent unbind at runtime by setting suppress_bind_attrs flag.
