From 87abf2ba3846d28e4b5f0e5f9cef873b4352a0a9 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Tue, 23 Feb 2021 13:45:37 -0800 Subject: [PATCH] firmware: qcom_scm: Suppress sysfs bind attributes 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.
