 Log Message:
 drm: Fix locking around accurate vblank counts.
 
 - Make drm_crtc_accurate_vblank_count require the caller to hold the
   event lock, rather than take it internally.
 
 - Fix locking around drm_crtc_accurate_vblank_count and related
   operations in amdgpu and nouveau interrupt handlers.
 
 - Use drm_crtc_vblank_put_locked, not drm_crtc_vblank_put, when we
   already hold the event lock.
