From: Arnd Bergmann <[email protected]>

Without this header, the newly added code fails to build:

Applied, thanks!

[1/1] drm/rockchip: rk3066_hdmi: include drm/drm_atomic.h
commit: f4814c20d14ca168382e8887c768f290e4a2a861

Very puzzling, I did testbuild with the atomic conversion in place
and also re-did it again to before applying this patch and didn't get
the mentioned error - not sure what I might have done differently to
create a dufferent reszkt,

In any case, I applied the fix.


Best regards,
