[PATCH] 8250: uniphier: allow modular build with 8250 console
From: arnd@arndb.de (Arnd Bergmann)

Subsystem:
8250/16?50 (and clone uarts) serial driver, arm/uniphier architecture, the rest, tty layer and serial drivers · Maintainers:
Greg Kroah-Hartman, Kunihiko Hayashi, Masami Hiramatsu, Linus Torvalds, Jiri Slaby
The recently added uniphier 8250 port driver supports early console
probing, and it supports being built as a module, but the combination
of the two fails to link:
ERROR: "early_serial8250_setup" [drivers/tty/serial/8250/8250_uniphier.ko] undefined!
Given that earlycon support in a loadable module makes no sense,
making that code conditional on 'MODULE' is a correct solution.
