[PATCH 0/3] ASoC: snprintf() usage fixes

Hi,

this is a series of patches I spotted during debugging other code.
Intel skl and ASoC PCM core invokes succeeding calls of snprintf()
with the incorrect expectation of the return value, which may lead to
a buffer overflow.

The first patch is yet another bug I found during working on this, and
it's rather a real bug that can be seen clearly.
