During a system-wide suspend of devices, dpm_noirq_suspend_devices(), dpm_suspend_late() and dpm_suspend() move devices from one list to another. They do it with each device after its PM callback in the given suspend phase has run or has been scheduled for asynchronous execution, in case it is deleted from the current list in the meantime. However, devices can be moved to a new list before invoking their PM callbacks (which usually is the case for the devices whose callbacks are executed asynchronously anyway), because doing so does not affect the ordering of that list. In either case, each device is moved to the new list after the previous device has been moved to it or gone away, and if a device is removed, it does not matter which list it is in at that point, because deleting an entry from a list does not change the ordering of the other entries in it. Accordingly, modify the functions mentioned above to move devices to new lists without waiting for their PM callbacks to run regardless of whether or not they run asynchronously. No intentional functional impact. 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 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.
