I might use "error->{g,h}uc_fw.path" as the condition, for both
individually. We will have DMC here in the future, too.
That's the type of predicate I was looking for. If we can tell when the
fw has been loaded just by looking at the uc_fw struct, please do so.
If you want to include uc fw info only when fw was loaded at capture
moment,
then we can look directly at its "load_status" field:
if (error->guc_fw.load_status == INTEL_UC_FIRMWARE_SUCCESS)
But what if fw was loaded earlier, before error capture is started?
Don't we want to capture whole driver configuration?
