ALSA: caiaq: input: Add error handling for unsupported input methods in `snd_usb_caiaq_input_init`
[ Upstream commit 0d727e1856ef22dd9337199430258cb64cbbc658 ]
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.
Fixes: 523f1dce3743 ("[ALSA] Add Native Instrument usb audio device support")
