Merge series "ASoC: SOF: simplify probe and report errors" from Ranjani...

Merge series "ASoC: SOF: simplify probe and report errors" from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:

These patches simplify the sof_probe_complete handling and
address reporting of errors during probe.

Peter Ujfalusi (2):
  ASoC: SOF: core: Add missing error prints to device probe operation
  ASoC: SOF: Simplify sof_probe_complete handling for acpi/pci/of
