ALSA: Introduce snd_card_create()
Introduced snd_card_create() function as a replacement of snd_card_new(). The new function returns a negative error code so that the probe callback can return the proper error code, while snd_card_new() can give only NULL check. The old snd_card_new() is still provided as an inline function but with __deprecated attribute. It'll be removed soon later. Signed-off-by: Takashi Iwai <tiwai@suse.de>
