From f24640648186b59bd39f8cd640d631bdb61a3197 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 29 Jan 2014 12:13:43 +0100 Subject: ALSA: Use standard device refcount for card accounting Drop the own refcount but use the standard device refcounting via get_device() and put_device(). Introduce a new completion to snd_card instead of the wait queue for syncing the last release, which is used in snd_card_free().
