[PATCH] drm: export crtc_ww_class

[PATCH] drm: export crtc_ww_class

[Rob Clark]

kbuild noticed this:

  ERROR: "crtc_ww_class" [drivers/gpu/drm/msm/msm.ko] undefined!

because crtc_ww_class is referenced by drm_modeset_lock_init() which is
static-inline in a header file.

I guess we hadn't noticed yet because no driver so far is creating their
own modeset-locks.  That changes with the msm/mdp5 patches I have lined
up for atomic hwpipe and SMP block assignment.
