[ Upstream commitb4fa73358c] The patch fix two reference leak. 1) pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to call put operation will result in reference leak. 2) The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. We fix it by: 1) adding call pm_runtime_put_noidle or pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable in error handling, to keep usage counter and disable depth balanced.

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.
