If the 8250 driver is built as a module (or built-in without console support) the Freescale specific workaround were silently not activated. Add a warning in this case. Currently CONFIG_SERIAL_8250_FSL=y implies that the function fsl8250_handle_irq() is built-in and can be used. However with the changes of the next commit CONFIG_SERIAL_8250_FSL might be enabled also when the 8250 driver is a module and so more care is needed when fsl8250_handle_irq() is to be used. The code added here is able to handle the new situation already.

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 Restructured Text 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.
