Ruliang Lin 962f1c8c0c ALSA: caiaq: input: Add error handling for unsupported input methods in snd_usb_caiaq_input_init 
[ Upstream commit 0d727e1856 ]

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.
