mv_ehci_enable() did not disable and unprepare clocks in case of failures of phy_init(). Besides, it did not take into account failures of ehci_clock_enable() (in effect, failures of clk_prepare_enable()). The patch fixes both issues and gets rid of redundant wrappers around clk_prepare_enable() and clk_disable_unprepare() to simplify this a bit.

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.
