Comment 89 for bug 1551041

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/ice1712/ice1712.c?id=4f8e940095536bc002a81666a4107a581c84e9b9

The fix for the other driver in the original bug report

It look like au88x0 pointer callback does not return zero when interrupt occur, just 2 or 3 frames pass the period boundary, the pcm core only regard this error when ptr pass the buffer

However, it is strange that pcm_avail.c return 1024
