+Subject: [PATCH] of: Move of_modalias() to module.c
+
+Create a specific .c file for OF related module handling.
+Move of_modalias() inside as a first step.
+
+The helper is exposed through of.h even though it is only used by core
+files because the users from device.c will soon be split into an OF-only
+helper in module.c as well as a device-oriented inline helper in
+of_device.h. Putting this helper in of_private.h would require to
+include of_private.h from of_device.h, which is not acceptable.
