Replace "ret" variable by "irq" variable from platform_get_irq condition handling in stm32_init_port as suggested by Jiri in "STM32 uart cleanup and improvement" series review. This change will prevent port->irq to be unexpectly modified by a potential change of "ret" value introduced by a new patch.

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.
