We need a way to send extra parameters to DSP firmware. In order to do
this, we introduce ext_data array at the end of ipc_stream_params.

With this new addition we can send compress parameters.

This requires SOF ABI bump.

Daniel Baluta (4):
  ASoC: SOF: compress: Dynamically allocate pcm params struct
  ASoC: SOF: Copy compress parameters into extended data
  ASoC: SOF: compress: Prevent current kernel running with older FW
  uapi: sof: abi: Bump SOF ABI for ext_data_length
