From: "Keqiao, Zhang" <keqiao.zhang@xxxxxxxxx>
alsabat reports -86 error when system suspend and resume. Check the
return value of read_to_pcm() and write_to_pcm(), when -x8 err is
detected, do resume and wait for read/write to pcm to complete.
Write PCM device error: Streams pipe error(-86)
Read PCM device error: Streams pipe error(-86)
*** Error in alsabat: double free or corruption (out): 0x00007fb438001810 ***
