[ Upstream commit b032ae57d4fe2b2445e3bc190db6fcaa8c102f68 ]
If the clock pep->clk was not enabled in pxa168_eth_probe,
it should not be disabled in any path.
Conversely, if it was enabled in pxa168_eth_probe, it must be disabled
in all error paths to ensure proper cleanup.
Use the devm_clk_get_enabled helper function to ensure proper call balance
for pep->clk.

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.
