[ Upstream commit d46c4c839c20a599a0eb8d73708ce401f9c7d06d ]
Commit 03f1444016b7 ("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 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.
