Bug Description
On my Dell XPS 13 9343, the microphone works fine with the vivid kernel. However, it does not work with the current 4.0 wily kernel unless I patch it with these commits:

For unrelated reasons, I decided to try the wily 4.1 kernel found here: https:/
Note I am running vivid userspace, the 4.1 wily kernel from the ppa, bcmwl-kernel-source from wily (since there is a dkms fix) and linux-firmware from wily.

We had both of those commits backported in vivid, but it seems they got lost when rebasing onto 4.0, so that accounts for the regression there.
In 4.1 the commits are there, but it seems this commit causes a regression:
