Many of the tty functions were converted to use a struct tty_port

I tested that this does indeed fix the build warnings. I didn't test the
resultant driver.
I wonder if this would have been caught earlier if it had errored out
instead of outputting lots of warnings. Looking at the gcc documentation
there doesn't seem to be a way to turn this kind of warning into an
error. That would leave -Werror as the only option to have the compiler
abort on this kind of warning.
Globally enabling -Werror might not be a good idea and I'm sure it must
have been discussed in the past (even though Google doesn't show any
references). In this particular case the warnings are actually severe
errors and are very likely to cause buggy behaviour so it would be good
to catch them at compile time. Warnings are unfortunately quite easy to
ignore.
I know I can always use EXTRA_CFLAGS to change this for local builds,
but maybe getting more people to do this would be worthwhile.
There was no issue when patch created. The change happen in the api with
same time when patch created and so become out of sync.
API changed with commit on 1/16. Serial driver also get added on 1/16.
