In general, wakeup settings are not supposed to be changed during any of the system wide PM phases. The reason is simply that it would break guarantees provided by the PM core, to properly act on active wakeup sources. However, there are exceptions to when, in particular, disabling a device as wakeup source makes sense. For example, in cases when a driver realizes that its device is dead during system suspend. For these scenarios, we don't need to care about acting on the wakeup source correctly, because a dead device shouldn't deliver wakeup signals. To this reasoning and to help users to properly manage wakeup settings, let's print a warning in cases someone calls device_wakeup_enable() during system sleep. Suggested-by: Rafael J.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
