[SCSI] megaraid_sas: remove sysfs poll_mode_io world writeable permissions
/sys/bus/pci/drivers/megaraid_sas/poll_mode_io defaults to being world-writable, which seems bad (letting any user affect kernel driver behavior). This turns off group and user write permissions, so that on typical production systems only root can write to it. Signed-off-by: Bryn M.
