4.9-stable review patch. If anyone has any objections, please let me know.

From: Takashi Iwai tiwai@suse.de
commit d5a6cabf02210b896a60eee7c04c670ee9ba6dca upstream.
Some Lenovo laptops, e.g. Lenovo P50, showed the pop noise at resume or runtime resume. It turned out to be reduced by applying alc_no_shutup() just like TPT440 quirk does.
Since there are many Lenovo models showing the same behavior, put this workaround in ALC269_FIXUP_THINKPAD_ACPI entry so that it's applied commonly to all such Lenovo machines.
