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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
