Commit ordering / path inconsistency (important for clean history)
Create files directly in Runner/suites/Kernel/Baseport/USB/usb_uac/ from patch 1 onward, and drop patch 4/4 entirely.
Alternative:
Move patch 4/4 earlier (as 1/4), then add script/README/YAML into the final location.
The shell script verifies the enumeration of USB Audio Class devices. Signed-off-by: Aanchal Chaurasia <achauras@qti.qualcomm.com>
Added setup information and basic requirements. This informs the tester of the hardware setup requirement before starting test. Signed-off-by: Aanchal Chaurasia <achauras@qti.qualcomm.com>
Individual test definition is meant to be used for debugging the test script running in LAVA. Signed-off-by: Aanchal Chaurasia <achauras@qti.qualcomm.com>

Distinguish playback-only vs capture-only devices and also log bound driver info from sysfs

Consider whether “no UAC device attached” should be FAIL or SKIP
