Subject: [PATCH v2] 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

warning: drivers/tty/serial/8250.c,3348: line over 80 characters
This warning remains, and should be ignored:
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.

Changes in v2:
- Fixed line continuation problems (and unnecessary ones)
- Tidied up code style in response to comments
- Update commit message to mention I am ignoring one warning
- Use pr_info_ratelimited() instead of printk_ratelimited(KERN_INFO...)
