Kai-Heng Feng ee3c5b644a iio: light: cm32181: Fix PM support on system with 2 I2C resources 
Commit c1e62062ff ("iio: light: cm32181: Handle CM3218 ACPI devices
with 2 I2C resources") creates a second client for the actual I2C
address, but the "struct device" passed to PM ops is the first I2C
client that can't talk to the sensor.

That means the I2C transfers in both suspend and resume routines can
fail and blocking the whole suspend process.

Instead of using the first client for I2C transfer, use the I2C client
stored in the cm32181 private struct so the PM ops can get the correct
I2C client to really talk to the sensor device.

Fixes: 68c1b3dd5c ("iio: light: cm32181: Add PM support")

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.
