## Overview

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: debug: Fix potential buffer overflow by snprintf()

snprintf() returns the would-be-filled size when the string overflows
the given buffer size, hence using this value may result in the buffer
overflow (although it's unrealistic).

This patch replaces with a safer version, scnprintf() for papering
over such a potential issue.

- `Linux >= 5b10b62989219aa527ee4fa555d1995a3b70981b < 1eb123ce985e6cf302ac6e3f19862d132d86fa8f`
