From 19e7bf836997f37b7c70cf8f3091e76b79769673 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 16 Feb 2022 13:42:24 +0530 Subject: [PATCH] remoteproc: wkup_m3: Set sysfs_read_only flag The Wakeup M3 remote processor is controlled by the wkup_m3_ipc client driver, so set the newly introduced 'sysfs_read_only' flag to not allow any overriding of the remoteproc firmware, state, recovery, or coredump from userspace.
