Bug Description
[Impact]
amdgpu generates assert warning messages when retimer is not supported.
This behaviour can cause confusions to users.
[Fix]
This is fixed by commit a0e40018dcc3f59a. It silences ASSERTs by
outputing a debug message and exiting when retimer is not supported by
hardware.
[Test]
Verified on B450 I AORUS PRO WIFI with AMD Ryzen 3 3200G as discussed
on LP:1871248.
[Regression Potential]
Low. It is for unsupported hardware features, and the patch was cherry-picked
from upstream kernel 5.7 rc1.
