commit64c7d7ea22upstream. clk_pm_runtime_get() assumes that the PM-runtime usage counter will be dropped by pm_runtime_get_sync() on errors, which is not the case, so PM-runtime references to devices acquired by the former are leaked on errors returned by the latter. Fix this by modifying clk_pm_runtime_get() to drop the reference if pm_runtime_get_sync() returns an error.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
