ALSA: x86: Fix racy access to chmap The access to chmap can be racy against the hotplug process, where it recreates the chmap on the fly. For protecting against it, a mutex is introduced in this patch. It's also used for protecting the change / reference of eld and state fields, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
