Subject: [PATCH] soc: qcom: rpmh-rsc: Set suppress_bind_attrs flag
Git-commit: 1a53ce9ab4faeb841b33d62d23283dc76c0e7c5a
Patch-mainline: v5.9-rc1
References: git-fixes

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.
