Linux kernel puts strict limits on which functions and data structures are available to loadable kernel modules; only those that have been explicitly exported with EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() are accessible. In the case of EXPORT_SYMBOL_GPL(), only modules that declare a GPL-compatible license will be able to see the symbol. Since the whole drm_of.c file is declared with GPL-2.0-only license, so let us keep functions in that source file consistently.
