Hi Mark, Vinod Cc Laurent, Hiep-san
These are v2 of fixup unknown interrupt issue patch which was reported by Hiep-san in v4.1-rcX kernel. It was not happened in v4.0 because ARM platform side couldn't use DMA transfer.
We tested these same as v1 patches, and confirmed these solved problem
Hiep-san, can you please re-test these patches ?

We re-tested these patches on our Lager board. (30 times playback + 10 minutes recode and playback) It works very well without any problems,
Best Regards, Cao Minh Hiep.
