    drm: Remove drm_modeset_(un)lock_crtc
    
    The last user, the cursor ioctl, can just open-code this too. We
    simply have to move the acquire ctx dance from the universal function
    up into the top-level ioctl handler.

Currently the drm-next tree, agd5f's drm-4.12-wip tree are failing, the intel nightly tree is working as is Linus's tree.

Seems there is a fix, but it isn't in drm-next yet.
