[PATCH 4/6] firmware: qcom_scm: Suppress sysfs bind attributes

From: Stephen Boyd
Date: Tue Feb 23 2021 - 16:47:30 EST


We don't want userspace ejecting this driver at runtime. Various other
drivers call into this code because it provides the mechanism to
communicate with the secure world on qcom SoCs. It should probe once and
be present forever after that.
