The commit 0c65b2b90d ("net: of_get_phy_mode: Change API to solve
int/unit warnings") updated the function of_get_phy_mode declaration.
Now it returns an error code and in case the node doesn't contain the
property 'phy-mode' or 'phy-connection-type' it returns -EINVAL and would
set the phy_interface_t to PHY_INTERFACE_MODE_NA.
Ocelot VSC7514 has 4 internal phys which have the phy interface
PHY_INTERFACE_MODE_NA. So because of_get_phy_mode would assign
PHY_INTERFACE_MODE_NA to phy_mode when there is an error, there is no need
to add the error check.
Updates for v2:
- drop error check because of_get_phy_mode already assigns phy_interface
to PHY_INTERFACE_MODE in case of error.

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.
