Two deadly typos break RX and TX traffic on the VSC8502 PHY using RGMII
if phy-mode = "rgmii-id" or "rgmii-txid", and no "tx-internal-delay-ps"
override exists. The negative error code from phy_get_internal_delay()
does not get overridden with the delay deduced from the phy-mode, and
later gets committed to hardware. Also, the rx_delay gets overridden by
what should have been the tx_delay.
Fixes: dbb050d2bf ("phy: mscc: Add support for RGMII delay configuration")

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.
