Refactor the code in charge of looking up the USB PHY when no platdata is provided. Attempt to get a generic USB PHY first, then look for a legacy USB PHY through device-tree and finally get any registered PHY with the correct type. This way, only a single USB PHY is obtained and the flow is easier to understand and follow. All error pointers (except for EPROBE_DEFER) are considered as PHY not found.

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.
