Subject: [PATCH AUTOSEL 5.7 02/60] soc: qcom: rpmh-rsc: Set suppress_bind_attrs flag
Date: Mon, 10 Aug 2020 15:09:30 -0400 [thread overview]
Message-ID: <20200810191028.3793884-2-sashal@kernel.org> (raw)
In-Reply-To: <20200810191028.3793884-1-sashal@kernel.org>
From: Maulik Shah <mkshah@codeaurora.org>
[ Upstream commit 1a53ce9ab4faeb841b33d62d23283dc76c0e7c5a ]
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.
