pm_runtime_suspended() only checks the current runtime PM status and does not modify it, making it ineffective in this context. This could result in improper power management if the device remains active when removed. This patch fixes the issue by introducing a check with pm_runtime_status_suspended() to determine if the device is already suspended. If it is not, it calls imx334_power_off() to power down the device and then uses pm_runtime_set_suspended() to correctly update the runtime PM status to suspended.

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 reStructuredText 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.
