[PATCH] ASoC: SOF: Fix probe point getter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Firmware API changes which introduced 'num_elems' param in several probe
structs such as sof_ipc_probe_dma_add_params also impacted getter for
both, DMA and probe points. All struct handlers except for
sof_ipc_probe_info_params have been updated. Align said handler too to
calculate payload size correctly.
