+From: Stephen Warren <swarren@xxxxxxxxxx>
+
+When tegra-drm.ko is built as a module, these MODULE_DEVICE_TABLEs allow
+the module to be auto-loaded since the module will match the devices
+instantiated from device tree.
+
+(Notes for stable: in 3.14+, just git rm any conflicting file, since they
+are added in later kernels. For 3.13 and below, manual merging will be
+needed)
+
+Cc: <stable@xxxxxxxxxxxxxxx>

+v2: Remove change to drm.c, since the match table there isn't used for
+probing.
