keep the DRM include statements sorted alphabetically.

Ok, that's a bit too much. :D

First of all, it's still not alphabetically. Second, linux headers go first, then drm headers follow. It should look like

 #include <linux/...>
 #include <linux/...>
 #include <linux/...>

 #include <drm/...>
 #include <drm/...>
 #include <drm/...>

with each block sorted alphabetically.

If you include drm_managed.h right before drm_print.h, it should be fine already.

Best regards
Thomas
