Title:
  update-initramfs complains of missing amdgpu firmware files

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Focal:
  Fix Committed

Bug description:
  SRU Justification

  Impact: amdgpu references firmware files in modinfo which have not
  been supplied to linux-firmware. This causes update-initramfs to
  generate "Possible missing firmware" warnings.

  Fix: Since the firmware is not available, all we can do is remove the
  files from modinfo.

  Test Case: Confirm that update-initramfs no longer produces the
  warnings.

  Regression Potential: Low. If someone had managed to obtain these
  files they will no longer be added to the initramfs, potentially
  causing regressions for these users. This would be an atypical
  situation.
