-Request memory regions in all drivers

+Request memory regions in all fbdev drivers
+--------------------------------------------
 
-Go through all drivers and add code to request the memory regions that the
-driver uses. This requires adding calls to request_mem_region(),
-pci_request_region() or similar functions. Use helpers for managed cleanup
-where possible.
+Old/ancient fbdev drivers do not request their memory properly.
+Go through these drivers and add code to request the memory regions that the
+driver uses. Problematic areas include hardware that has exclusive ranges like
+VGA. VGA16fb does not request the range as it is expected.
 
 Drivers are pretty bad at doing this and there used to be conflicts among
 DRM and fbdev drivers. Still, it's the correct thing to do.
