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.

Both acpi_pci_need_resume() and acpi_dev_needs_resume() check if the current ACPI wakeup configuration of the device matches what is expected as far as system wakeup from sleep states is concerned, as reflected by the device_may_wakeup() return value for the device. However, they only should do that if wakeup.flags.valid is set for the device's ACPI companion, because otherwise the wakeup.prepare_count value for it is meaningless. Add the missing wakeup.flags.valid checks to these functions. Signed-off-by:Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by:
