    Subject[PATCH 02/79] serial: bfin_5xx: fix building as module when early printk is enabled
    Date
    From: Mike Frysinger <vapier@gentoo.org>

    Since early printk only makes sense/works when the serial driver is built
    into the kernel, disable the option for this driver when it is going to be
    built as a module. Otherwise we get build failures due to the ifdef
    handling.
