commit 97264eaaba0122a5b7e8ddd7bf4ff3ac57c2b170 upstream. If the clocks priv->iclk and priv->fclk were not enabled in ehci_hcd_sh_probe, they should not be disabled in any path. Conversely, if they was enabled in ehci_hcd_sh_probe, they must be disabled in all error paths to ensure proper cleanup. Found by Linux Verification Center (linuxtesting.org) with Klever. Fixes:63c8455222("usb: ehci-hcd: Add support for SuperH EHCI.")

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.
