There is no need to read the version register twice, once in stmmac_get_id() and then again in stmmac_get_dev_id(). Consolidate this into stmmac_get_version() and pass each of these this value. As both functions unnecessarily issue the same warning for a zero register value, also move this into stmmac_get_version().

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.
