Commit03f1444016("PM: sleep: Fix handling devices with direct_complete set on errors") caused power.is_suspended to be set for devices with power.direct_complete set, but it forgot to ensure the clearing of that flag for them in device_resume(), so power.is_suspended is still set for them during the next system suspend-resume cycle. If that cycle is aborted in dpm_suspend(), the subsequent invocation of dpm_resume() will trigger a device_resume() call for every device and because power.is_suspended is set for the devices in question, they will not be skipped by device_resume() as expected which causes scary error messages to be logged (as appropriate). To address this issue, move the clearing of power.is_suspended in device_resume() immediately after the power.is_suspended check so it will be always cleared for all devices processed by that function.

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.
