Hi Chris.

I dunno this code - but patch is obviously correct.
This diff is a bit weird as it shows that another function is moved.
But it makes sense looking at drm_pci.c

My I suggest to change the commit message slightly, because the patch
actually moves drm_pci_agp_destroy(). Something along 'implement
_destroy() before _init() to protect the latter by CONFIG_DRM_LEGACY'
should do.

In any case
