Title:
  v4l2loopback 10.0-1ubuntu1 ADT test failure with linux
  5.0.0-14-generic

Status in v4l2loopback package in Ubuntu:
  In Progress

Bug description:
  [ Impact ]

  The DKMS package fails to install on kernels based on 5.0;
  specifically noticed in the Bionic HWE Edge kernel.

  [ Test Case ]

  Install the v4l2loopback-dkms package with a 5.0 kernel. The package
  should install without any errors.

  [ The Problem ]

  "do_gettimeofday" was deprecated and removed in the 5.0 kernels, so
  the package will not compile since the function it requires does not
  exist.

  [ Proposed Fix ]

  Port the following patch from the package developers which replaces
  calls to the deprecated API with appropriate wrapper functions:
  https://github.com/umlaeute/v4l2loopback/commit/afe0b233070d7ca5d6df83c5f2723d276dcd287d.patch

  [ Regression Potential ]

  I think regression potential is low if the proposed fix is accepted.
  The function calls that supplant the deprecated ones have been there
  since before kernel 4.15 (of which Bionic is based upon).
