This commit (09838c4efe9a) broke boot for me. These two hunks in
particular:

I hacked up patch to use help->disable/help->enable if atomic_ versions
are NULL. It worked.

In my setup I stepped onto nv50_msto_help->atomic_enable == NULL. But
there are two more drm_encoder_helper_funcs in dispnv50/disp.c that don't
have atomic_enable/disable set: nv50_dac_help, nv50_pior_help.
