From 1ca2f2ec9e74e9d6e398e09b6468b4462c6d6b6e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 24 Jun 2013 15:51:54 +0200 Subject: ALSA: vmaster: Add snd_ctl_sync_vmaster() helper function Introduce a new helper function, snd_ctl_sync_vmaster(), which updates the slave put callbacks forcibly as well as calling the hook. This will be used in the upcoming patch in HD-audio codec driver for toggling the mute in vmaster slaves. Along with the new function, the old snd_ctl_sync_vmaster_hook() is replaced as a macro calling with the argument hook_only=true.
