Subject: [PATCH 5/5] remoteproc/wkup_m3: Set deny_sysfs_ops flag
Date: Fri, 14 Sep 2018 19:37:25 -0500 [thread overview]
Message-ID: <20180915003725.17549-6-s-anna@ti.com> (raw)
In-Reply-To: <20180915003725.17549-1-s-anna@ti.com>
The Wakeup M3 remote processor is controlled by the wkup_m3_ipc
client driver, so set the newly introduced 'deny_sysfs_ops' flag
to not allow any overriding of the remoteproc firmware or state
from userspace.
