[PATCH v1] ASoC: qcom: qdsp6: Fix references to lookup USB_RX mixer status

From: Wesley Cheng
Date: Fri Apr 11 2025 - 15:27:22 EST


This addresses a change in the USB RX mixer naming that was updated in the
following commit:

commit 450d63471d1c ("ASoC: qcom: qdsp6: Introduce USB AFE port to q6dsp")

In order for the USB SND offload mixer to reference the correct PCM device
index, the q6usb_usb_mixer_enabled() is used to match the mixer associated
to the FE multimedia DAI, so the naming has to match. Update the string
lookup and comments with the proper "USB_RX Audio Mixer" tag.

Fixes: e0dd9240f13a ("ASoC: qcom: qdsp6: Fetch USB offload mapped card and PCM device")
