Not introduced by this patch, but the "|| ARM" looks strange to me.
Is this meant for compile-testing? Doesn't the driver compile on all
platforms (it does on m68k), so "|| COMPILE_TEST" is not appropriate?
Is the CAN FD controller present on some Renesas arm32 SoCs (but
not yet supported by this driver)?
