From ecbcfe36fa882e9f8f2be63ac0c42978336bf997 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 5 Sep 2005 17:15:37 +0200 Subject: [ALSA] Introduce snd_card_set_generic_dev() ALSA Core A new function snd_card_set_generic_dev() is introduced to add the 'generic device' support for devices without proper bus on sysfs. It's a last resort, and should be removed in future when they have a proper bus, instead.
