Bennett <g@xxxxx> Date: Wed Dec 20 04:07:00 2023 +1030 ALSA: scarlett2: Add missing error check to scarlett2_config_save() [ Upstream commit 5f6ff6931a1c0065a55448108940371e1ac8075f ] scarlett2_config_save() was ignoring the return value from scarlett2_usb(). As this function is not called from user-space we can't return the error, so call usb_audio_err() instead. Signed-off-by: Geoffrey D.
