Ok, it's really weird that we cannot determine the firmware/driver
combination which cause the DSP lock. I would propose to block the older
firmware load <1.4 (or 1.4.2 which has the correct firmware version!)
then (at least with a big warning or module option which is off by
default) for the newer kernels.
The driver has no information on firmware version until the FW_READY
IPC, so we can't block the load. And with the firmware handling
happening in a work queue, blocking will not result in a failed probe.
IIRC those timing issues are only for the HDaudio link DMA, I don't
think we had issues with DMIC or SSP.
A warning urging people to update the firmware is probably easier to
implement.
It makes sense. At least a hint that something may be wrong. I believe that it
might help to identify issues.
