Coccinnelle reports a warning Warning: Use scnprintf or sprintf Following the advice on kernel documentation https://www.kernel.org/doc/html/latest/filesystems/sysfs.html For show(device *...) functions we should only use sysfs_emit() or sysfs_emit_at() especially when formatting the value to be returned to user space.
