The version of rtl8821ce in the proposed pocket of Jammy that was
purported to fix this bug report has been removed because one or more
bugs that were to be fixed by the upload have failed verification and
been in this state for more than 10 days.

Title:
  rtl8821ce fails to build when CONFIG_CFG80211 is not enabled for
  linux-kvm

Status in ubuntu-kernel-tests:
  New
Status in rtl8821ce package in Ubuntu:
  Confirmed
Status in rtl8821ce source package in Jammy:
  Won't Fix

Bug description:
  [SRU Justification]

  Impact:
  jammy:linux-kvm does not have CONFIG_CFG80211 enabled.
  Module rtl8821ce-dkms requires it, otherwise build will fail.
  Build was not performed before because of this rule:

  # Only build on wifi enabled kernels
  if ! grep -q '^CONFIG_CFG80211=[ym]$' $kernel_source_dir/.config; then
  BUILD_EXCLUSIVE_KERNEL="^$"
  fi

  But in the last update: 5.5.2.1-0ubuntu11~0.22.04.1 this was overridden by
  BUILD_EXCLUSIVE_KERNEL="^5.15.*"
  instead of appending the new exclude rule.

  This lead to new regression in autopkgtest for jammy:linux-
  kvm-5.15.0-1029.34.

  Fix:
  Append the last rule:

  BUILD_EXCLUSIVE_KERNEL+=" ^5.15.*"

  Tescase:
  autopkgtest rtl8821ce fails during build with the error from below

  Regression potential:
  None. Build is skipped so no tests are performed.
