ASoC: SOF: Intel: hda: don't send DAI_CONFIG IPC for older firmware
Browse files Browse the repository at this point in the history
BE hw_params op was recently added for SSP type DAIs.
But sending the DAI_CONFIG IPC during hw_params
is not supported with older firmware. So add an ABI check
to avoid sending the IPC if the firmware ABI is older than
3.18.

Fixes: e12be9f ('ASoC: SOF: Intel: HDA: add hw params callback for SSP DAIs')
