Vitalii Mordan 4a04ce0bc9 usb: ehci-spear: fix call balance of sehci clk handling routines
commit 40c974826734836402abfd44efbf04f63a2cc1c1 upstream.

If the clock sehci->clk was not enabled in spear_ehci_hcd_drv_probe,
it should not be disabled in any path.

Conversely, if it was enabled in spear_ehci_hcd_drv_probe, it must be disabled
in all error paths to ensure proper cleanup.

Found by Linux Verification Center (linuxtesting.org) with Klever.

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.
