I forgot to #include <drm/drm_drv.h> for those platforms and didn't notice
because I only tried to build for X86. I'll fix it.

I built this patch against drm-next, which currently points to v5.15-rc1.

Should I be targeting a different branch? In any case, as suggested, I'll
remember to use "--base" in the future to make it easier to apply. Thanks for
the hint.

Out of curiosity: The top comment says there were two build errors (one on
exynos and another one on tegra), but there is only one reported bug (on msm).

Is this because the bot only reports the first error found? Is there a link to
a report with each of the build errors on each of the platforms?

Thanks.
