commit 64f43895b4457532a3cc524ab250b7a30739a1b1 upstream.
In the error path of iio_channel_get_all(), iio_device_put() is called
on all IIO devices, which can cause a refcount imbalance. Fix this error
by calling iio_device_put() only on IIO devices whose refcounts were
previously incremented by iio_device_get().
Fixes: 314be14bb8 ("iio: Rename _st_ functions to loose the bit that meant the staging version.")

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.
