#      "This is a bit bigger than I'd like, however it has two weeks of amdgpu
#       fixes in it, since they missed last week, which was very small.
#     
#       The nouveau regression is probably the biggest fix in here, and it
#       needs to go into 5.15 as well, two i915 fixes, and then a scattering
#       of amdgpu fixes. The biggest fix in there is for a fencing NULL
#       pointer dereference, the rest are pretty minor.
#     
#       For the misc team, I've pulled the two misc fixes manually since I'm
#       not sure what is happening at this time of year!
#     
#       The amdgpu maintainers have the outstanding runpm regression to fix
#       still, they are just working through the last bits of it now.
#     
#       Summary:
#     
#       nouveau:
#        - fencing regression fix
#     
#       i915:
#        - Fix possible uninitialized variable
#        - Fix composite fence seqno icrement on each fence creation
#     
#       amdgpu:
#        - Fencing fix
#        - XGMI fix
#        - VCN regression fix
#        - IP discovery regression fixes
#        - Fix runpm documentation
#        - Suspend/resume fixes
#        - Yellow Carp display fixes
#        - MCLK power management fix
#        - dma-buf fix"
