According to Documentation/filesystems/sysfs.rst, show() callback function should only use sysfs_emit() or sysfs_emit_at() instead of sprint() family functions when formatting the device attribute values to be returned to user space. Issue identified using the device_attr_show.cocci Coccinelle script.
