From: Takashi Iwai <tiwai@xxxxxxx> [ Upstream commit 37c4fd0db7c961145d9d1909ecab386fdf703c26 ] The HD-audio codec driver remove may happen also at dynamically unbinding during operation, hence it needs manual triggers of snd_device_disconnect() calls, while it's missing for the jack objects that are associated with the codec. This patch adds the manual disconnection call for jacks when the remove happens without card->shutdown (i.e. not under the full removal).
