Since pm_runtime_force_resume() requires pm_runtime_force_suspend() to be called before it on the same device, the runtime PM status of the device is RPM_SUSPENDED when it is called unless the device's runtime PM status is changed somewhere else in the meantime. However, even if that happens, the power.needs_force_resume check is still required to pass and that flag is only set by pm_runtime_force_suspend() once and it is cleared at the end of pm_runtime_force_resume(), so it cannot be taken into account twice in a row. According to the above, the pm_runtime_status_suspended(dev) check in pm_runtime_force_resume() is redundant, so drop it. Signed-off-by: Rafael J.

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.
