[ Upstream commit 3c3dd56f760da056e821ac177e3ad0de4209a435 ]
In case of the I2C client exposes the flag I2C_CLIENT_HOST_NOTIFY,
pm_runtime_get_sync is called in order to always keep active the
adapter. However later on, pm_runtime_put_sync is never called
within the function in case of an error. This commit add this
error handling.
Fixes: 72bfcee11cf8 ("i2c: Prevent runtime suspend of adapter when Host Notify is required")

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.
