Having this, guards like these work:
guard(serial8250_rpm)(up);
or
scoped_guard(serial8250_rpm, up) {
...
}
See e.g. "serial: 8250: use guard()s" later in this series.
And make them available to anyone (EXPORT + put in 8250.h) as drivers
open code this anyway.
The _tx ones are not defined as they would have no user.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
