[SRU][OEM-B-OSP1][PATCH 0/4] alsa/sof: fix the hang issue on Dell Nebula MP platforms

[Hui Wang]

BugLink: http://bugs.launchpad.net/bugs/1845904

[Impact]
Hanging after installation on Nebula MP.
Reported by ODM and we also can reproduce on the MP machine
that ODM provided

[Fix]
Intel debugged this issue for half month, finally they provided
4 patches to fix it. Intel tested these 4 patches on many many
sof machines, they worked well.

[Test Case]
Install oem image to Nebula MP machines, there is no hang anymore,
and the audio functions all work well.

[Regression Risk]
Low. Intel already tested these patches on many machines. And
we also teste them, the original issue is fixed by them and no
new issues found.
