ALSA: usb-audio: Inform the delayed registration more properly

Browse source

[ Upstream commit 7e1afce586 ]

The info message that was added in the commit a4aad5636c ("ALSA:
usb-audio: Inform devices that need delayed registration") is actually
useful to know the need for the delayed registration.  However, it
turned out that this doesn't catch the all cases; namely, this warned
only when a PCM stream is attached onto the existing PCM instance, but
it doesn't count for a newly created PCM instance.  This made
confusion as if there were no further delayed registration.

This patch moves the check to the code path for either adding a stream
or creating a PCM instance.  Also, make it simpler by checking the
card->registered flag instead of querying each snd_device state.
