Subject: [PATCH 4/6] firmware: qcom_scm: Suppress sysfs bind attributes
Date: Tue, 23 Feb 2021 13:45:37 -0800 [thread overview]
Message-ID: <20210223214539.1336155-5-swboyd@chromium.org> (raw)
In-Reply-To: <20210223214539.1336155-1-swboyd@chromium.org>
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.
