Kbuild robot pointed it out - of_matc_ptr should not be needed, even for
compile testing without OF.

I wonder whether it's better to add '#ifdef CONFIG_OF / #endif' around
the struct of_device_id declaration. I think it's what most drivers do,
even though I tend to prefer not adding #ifdefs making code less clean
only for COMPILE_TESTING.

No, most drivers added it long time ago before we switched it to a new
way - either __maybe_unused or without anything even. The point is that
OF driver can be reused for ACPI platforms. If you limit it with ifdef
or of_match_ptr, the ACPI platform won't have any table to use for binding.

Oh, I see, thanks for the clarification.

I wonder if it makes sense to mass-remove all of them and remove the macro.
