Hi,
I have succesfully installed latest amdgpu in my Ubuntu 20.04 5.15.0-53 hwe kernel.
Recently, I needed to change a usb kernel parameter with dpkg-reconfigure, which caused amdgpu to recompile:

Title: amdgpu-dkms-firmware 1:5.16.9.22.20.50200-1438746~20.04: amdgpu kernel module failed to build
The fix is simple:
src/amd/amdgpu/amdgpu_ttm.c:2313
adev->ssg.pgmap.ref = &adev->ssg.ref; -> adev->ssg.pgmap.ref = adev->ssg.ref;
I dunno how it compiled during installation. Anyway, plz fix:)
TIA
