  Bisect the kernel and found below fix from v5.15-rc1 mainline kernel

  [Test]
  Verified the patch on a Dell workstation with AMD W6800 graphics card

  [Where problems could occur]
  The code flow doesn't change much, but with better return codes handling and 
print out more meaningful messages. So it should not impact the already working 
devices.
