Removing ignore_suspend makes the PM succeeds. But it hits some other
ugly kernel bugs.
Okay have you marked .nonatomic = true for the machine DAIs?
Ah that's it. The patch below seems fixing the PM and the nonatomic
problems. I'm not sure about the nonatomic flag for the compress
stream, though.
Well we dont have upstream decoders so it wont be used in this case.
Also I fiddled only with FE. Do we need the same flags for BE? The
others don't look setting like that, so I left so.
I dont remember if BE needs or not FE should suffice.
OK then I leave it as is.
When I submit the fix, I should put Cc to stable, and wonder which
version we assure the nonatomic ops in SST driver. Did the code base
support nonatomic ops from the beginning?
can we take this opportunity to align all drivers?
The .nonatomic=true is set in all drivers for the BE, except for
cht_bsw_max98090_ti.c
It's either needed for all or not needed for all...
thanks,
Takashi
