[PATCH v33 31/31] ALSA: usb-audio: qcom: Notify USB audio devices on USB offload probing
From: Wesley Cheng
Date: Thu Jan 16 2025 - 18:32:37 EST
If the vendor USB offload class driver is not ready/initialized before USB
SND discovers attached devices, utilize snd_usb_rediscover_devices() to
find all currently attached devices, so that the ASoC entities are notified
on available USB audio devices.
