This is a preliminary patch for the later change to allow a better quirk ID management. In the current USB-audio code, there are a few places looking at usb_device idVendor and idProduct fields directly even though we have already a static member in snd_usb_audio.usb_id. This patch modifies such codes to refer to the latter field. For achieving this, two slightly intensive changes have been done: - The snd_usb_audio object is set/reset via dev_getdrv() for the given USB device; it's needed for minimizing the changes for some existing quirks that take only usb_device object. - __snd_usbmidi_create() is introduced to receive the pre-given usb_id argument. The exported snd_usbmidi_create() is unchanged by calling this new function internally. Signed-off-by: Takashi Iwai <tiwai@suse.de>
