Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit(). > ./drivers/scsi/hptiop.c:1114:8-16: WARNING: please use sysfs_emit > ./drivers/scsi/hptiop.c:1123:8-16: WARNING: please use sysfs_emit No functional change intended CC: HighPoint Linux Team <linux@xxxxxxxxxxxxxxxxxx> CC: "James E.J.
