Takashi Iwai 840311a09f ASoC: Intel: avs: Fix potential buffer overflow by snprintf()
commit ca3b7b9dc9bc1fa552f4697b7cccfa0258a44d00 upstream.

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

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