ASoC: SOF: Intel: MTL: Reduce the DSP init timeout
Browse files Browse the repository at this point in the history
20s seems unnecessarily large for the DSP init timeout. This coupled with
multiple FW boot attempts causes an excessive delay in the error path when
booting in recovery mode. Reduce it to 0.5s and use the existing
HDA_DSP_INIT_TIMEOUT_US.
