snd_intel_dsp_driver_probe page fault on linux 6.2

[Birgit Edel]

Workaround snd_intel_dspcfg.dsp_driver=1 allows sound output, did not investigate further.

Saw some upstream work mentioning "DSPless" mode that sounds like this might become relevant on 6.5 again.
Recent 6.5 report where DSP detect worked, but sound did not: LP: #2039320

Note that kvm_intel was loaded, also:
/sys/class/firmware-attributes/thinklmi/attributes/KernelDMAProtection/current_value:Enable
/sys/class/firmware-attributes/thinklmi/attributes/MicrophoneAccess/current_value:Disable
/sys/class/firmware-attributes/thinklmi/attributes/IntegratedAudioAccess/current_value:Enable
/sys/class/firmware-attributes/thinklmi/attributes/SGXControl/current_value:Disable

(in case some tool refuses parsing the dmesg cutout: I left the inserted "rmi4_smbus" message untouched)

DMAR: IOMMU enabled
SMT: disabled
microcode: Microcode Update Driver: v2.2.
