Takashi Iwai 6ee1310f4d ASoC: SOF: Intel: hda: Fix potential buffer overflow by snprintf()
[ Upstream commit 94c1ceb043c1a002de9649bb630c8e8347645982 ]

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.
