All functions and data types used by OF-specific code paths are declared
in <linux/of.h> regardless of CONFIG_OF. Replace the #ifdef CONFIG_OF
guard with a if(IS_SELECTED(CONFIG_OF)) and let the compiler optimize
the unused code away.

    You're using IS_ENABLED() actually.

Oops. We should fix gcc to check the commit messages :-)

Simon, could you fix this while applying, or should I resubmit ?
