If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit b32ae47a2b0a1fb4bd4942242847966d9b178222 upstream. The previous fix to handle the error from setup_card() caused a regression for the models that have no dedicated input device; snd_usb_caiaq_input_init() just returns -EINVAL, and we treat it as a fatal error although it should be ignored. As a regression fix, change the error code to -ENODEV, and ignore this error in the callee, to continue probing.
