Title:
  6.8.0-44 breaks amdgpu-dkms 6.8.5

Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  Ubuntu 24.04.1

  6.8.0-44 causes compile failure of amdgpu-dkms (6.8.5 from AMD
  partner)

  ```
  linux-image-generic                                      6.8.0-44.44          
                       amd64        Generic Linux kernel image

  amdgpu-dkms                    1:6.8.5.60200-2009582.24.04    amdgpu driver 
in DKMS format.                                                                 
       noble/main
  amdgpu-dkms-firmware           1:6.8.5.60200-2009582.24.04    firmware blobs 
used by amdgpu driver in DKMS format                                            
      noble/main
  ```

  The 6.8.0-44 kernel includes :

   * Noble update: upstream stable patchset 2024-07-25 (LP: #2074091)

      - drm/mst: Fix NULL pointer dereference at
  drm_dp_add_payload_part2    <---- This is the one

  This one causes a compile failure  in amdgpu-dkms 6.8.5  , detected
  from rocm6.2 users and initially reported there, but i believe it
  should be fixed in Ubuntu who backported the fix causing the bug.

  https://github.com/ROCm/ROCm/issues/3701#issuecomment-2351247361
  contains a trivial patch on the amdgpu-dkms side, but the problem is
  introduced by a patch on the kernel ubuntu-6.8.

  this is very annoying, and proposed workaround on github Amd Rocm are
  a bit weird (even if they work well)
