HID: hid-sensor-custom: Convert sprintf() family to sysfs_emit() family
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(). sprintf() and scnprintf() will be converted as well if they have.
