Patches are based on top of 4.19-rc1. The first 3 patches are independent of each other. Following is the patch summary: - Patch 1 fixes an issue with unbalanced sysfs start/stop and module removal - Patch 2 adds a minor additional check on firmware name being echoed into the sysfs file - Patch 3 is a minor kerneldoc fix. - Patches 4 and 5 introduce a new request denial to sysfs interfaces to not allow userspace to meddle with a remoteproc client driven boot flow, and usage of it by Wkup M3 remoteproc driver regards Suman Suman Anna (5): remoteproc: Fix unbalanced boot with sysfs for no auto-boot rprocs remoteproc: Check for NULL firmwares in sysfs interface remoteproc: Add missing kernel-doc comment for auto-boot remoteproc: Introduce deny_sysfs_ops flag remoteproc/wkup_m3: Set deny_sysfs_ops flag drivers/remoteproc/remoteproc_sysfs.c | 29 ++++++++++++++++++++++++++- drivers/remoteproc/wkup_m3_rproc.c | 1 + include/linux/remoteproc.h | 3 +++ 3 files changed, 32 insertions(+), 1 deletion(-) -- 2.18.0
