Linux kernel source tree
3487972d7f
Middle-layer code doing suspend-time optimizations for devices with the DPM_FLAG_SMART_SUSPEND flag set (currently, the PCI bus type and the ACPI PM domain) needs to make the core skip ->thaw_early and ->thaw callbacks for those devices in some cases and it sets the power.direct_complete flag for them for this purpose. However, it turns out that setting power.direct_complete outside of the PM core is a bad idea as it triggers an excess invocation of pm_runtime_enable() in device_resume(). For this reason, provide a helper to clear power.is_late_suspended and power.is_suspended to be invoked by the middle-layer code in question instead of setting power.direct_complete and make that code call the new helper.

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.
