ASoC: SOF: ipc4-topology: fixes for 'exotic' format
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
The introduction of 8bit and FLOAT formats missed to cover the
new corner cases they cause when the NHLT blobs are looked up.
The two patch in this series fixes the 8bit and FLOAT format caused
cases to be able to find the correct blob from NHLT.
