ALSA backport missing NVIDIA GPU codec IDs to patch table to Ubuntu 16.04 LTS Kernel

Patch is already found in v4.13 (ubuntu-artful)

$ git describe --contains 74ec118152ea494a25ebb677cbc83a75c982ac5f
v4.13~13^2~22

v4.4 (ubuntu-xenial) doesn't have the patch.

Since this seems trivial, and apply cleanly, and I'll proceed with the SRU (after verification) and see what kernel-team says.

I have provided a test kernel "4.4.0-111-generic #134+hf166707v20180117b5" for pre-SRU verification and it has been brought to my attention the following statement:

-----------------------------------------
Our QA was able to test with the kernel you provided, and things look good!

I've upgraded the kernel and issue did not repro.

Config :
GPU Driver 384.111
Kernel 4.4.0-111-generic

# uname -a
Linux <HOSTNAME> 4.4.0-111-generic #134+hf166707v20180117b5-Ubuntu SMP Wed Jan 17 19:04:03 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I've verified output through all channels (7.1) using Test Sound option in Sound Setting + by running different 4,6 channel clips using aplay.
Connections were made using DP-HDMI dongle (accell) + DENON-AVR

[PATCH][SRU][X] ALSA: hda - Add missing NVIDIA GPU codec IDs to patch table

- Eric

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I've let our QA (India-based) know about this. I'll update as soon as they've had a chance to verify.

Verified by our QA. Changing tag to "verification-done-xenial".

Thanks, Jamie, below steps were helpful.
This bug did not repro with [Ubuntu 16.04] + kernel 4.4.0-116-generic : 384.111 (R384_00)

I've verified output through all channels (7.1) using Test Sound option in Sound Setting + by running different 4,6 channel clips using aplay.
