Subject: [PATCH] serial: trivial checkpatch fixes in drivers/tty/serial/8250.c
This makes the file checkpatch clean, fixing these warnings:

warning: drivers/tty/serial/8250.c,3338: EXPORT_SYMBOL(foo); should
immediately follow its function/variable
warning: drivers/tty/serial/8250.c,3348: line over 80 characters
This warning remains, since I am not sure how to fix it:
error: drivers/tty/serial/8250.c,2929: Macros with complex values should
be enclosed in parenthesis
I am not sure if trivial includes all of the above - please let me know.
