Title:
  microphone regression on 4.1

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Fix Committed

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:
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=e1e62b98ebddc3234f3259019d3236f66fc667f8
  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=f3b703326541d0c1ce85f5e570f6d2b6bd4296ec

  For unrelated reasons, I decided to try the wily 4.1 kernel found
  here: https://launchpad.net/~canonical-kernel-
  team/+archive/ubuntu/ppa/. The microphone doesn't work even though
  Leann Ogasawara confirmed that the above two patches are included
  upstream.

  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.
