From 53fb1e63599438bd5f6fbb852023d80916d83983 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 28 Dec 2008 16:32:08 +0100 Subject: 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.
