Subject: serial: bfin_5xx: fix building as module when early printk is enabled
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=607c268ef9a4675287e77f732071e426e62c2d86;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

serial: bfin_5xx: fix building as module when early printk is enabled

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.
