[ Upstream commit780f629741] The PM reference count is not expected to be incremented on return in omap_i2c_probe() and omap_i2c_remove(). However, pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here. I Replace it with pm_runtime_resume_and_get to keep usage counter balanced. What's more, error path 'err_free_mem' seems not like a proper name any more. So I change the name to err_disable_pm and move pm_runtime_disable below, for pm_runtime of 'pdev->dev' should be disabled when pm_runtime_resume_and_get fails.

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.
