ALSA: caiaq: input: Add error handling for unsupported input methods in `snd_usb_caiaq_input_init`
Smatch complains that: snd_usb_caiaq_input_init() warn: missing error code 'ret' This patch adds a new case to handle the situation where the device does not support any input methods in the `snd_usb_caiaq_input_init` function. It returns an `-EINVAL` error code to indicate that no input methods are supported on the device.
