[SRU][Artful][Bionic][linux-oem][PATCH 0/2] fix headset-mic detection problem for two Dell machines

[Hui Wang]

BugLink: https://launchpad.net/bugs/1748807

We have two Dell machines which can't detect the headset microphone, as a result
can't record sound via headset mic.

One machchine has codec alc256, and there is already a quirk for this codec in the
driver, we just add its pin definition to pin quirk table (0002-xxx.patch).

The other machine has the codec alc289, we need the 0001-xxx.patch to let driver
support headset mode for alc289 first, then we add its pin definition to pin quirk
table (0002-xxx.patch)

[Test Case]
plug the headset and record the sound

[Fix]
two upstream commits

[Regression Potential]
low, since the 0001-xxx.patch just adds vendor id to existing driver to let
them support headset mode, it doesn't change existing functions, the 0002-xxx.patch
adds a group of pin definition, it doesn't change existing funcitons too.
