Subject: ASoC: SOF: Intel: hda-dai: Pass the CPU dai pointer
X-Git-Tag: v6.6.7~2882^2~8^2~151^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b436ed8dd071cae10ac3f94c541a783a094971ff;p=platform%2Fkernel%2Flinux-starfive.git

ASoC: SOF: Intel: hda-dai: Pass the CPU dai pointer

Pass the CPU DAI pointer from the ASoC core to hda_link_dma_hw_params() and
ipc3_hda_dai_trigger(). This will avoid looking up the CPU DAI pointer
multiple times.
