Qinglang Miao 780f629741 i2c: omap: fix reference leak when pm_runtime_get_sync fails
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.

README

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.
