[Robie Basak]

An upload of v4l2loopback to focal-proposed has been rejected from the
upload queue for the following reason: "Clearing this from the queue for
now as it isn't ready for an SRU to Focal. See
https://bugs.launchpad.net/ubuntu/+source/v4l2loopback/+bug/1921474/comments/12
and subsequent comments for details.".

Title:
  coverity bugs found in v4l2loopback dkms source

Status in v4l2loopback package in Ubuntu:
  Fix Released
Status in v4l2loopback source package in Focal:
  In Progress

Bug description:
  [SRU Justification]

  [Impact]

  On a MIPI camera through Intel IPU6 platform that its raw V4L2
  loopback interface is preserved for Intel Camera HAL libraries, a
  relay daemon + v4l2loopback is used to allow the usage of legacy V4L2
  based apps.

  v4l2loopback itself contains several potential issues that were
  identified by coverity tools. In order to prebuilt and sign this
  kernel module, these issues should be addressed first.

  [Test Plan]

  The changes here doesn't change the semantics of the implementation,
  and have no observable differences.

  [Where problems could occur]

  N/A.

  [Other Info]

  For Focal backports, 0.12.5-1 is equivalent to 0.12.3-1ubuntu0.3 plus
  micro version updates, so there should be little risk backport a new
  release, and we can drop additional patches carried. This implies bug
  1905613.

  This focal backport includes changes for bug 1921474, bug 1930208, and
  bug 1936250, so it will then become synced with Impish and newer
  again. The 0007-compliance-stop-
  declaring-V4L2_CAP_VIDEO_M2M-capabil.patch carried in bug 1930208 is
  deliberately skipped to avoid bug 1946660.
