From: Hui Wang hui.wang@canonical.com

commit d5078193e56bb24f4593f00102a3b5e07bb84ee0 upstream.

With the alc289, the Pin 0x1b is Headphone-Mic, so we should assign ALC269_FIXUP_DELL4_MIC_NO_PRESENCE rather than ALC225_FIXUP_DELL1_MIC_NO_PRESENCE to it. And this change is suggested by Kailang of Realtek and is verified on the machine.
