CVE-2022-50051

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.
