If a device referred to by ACPI LPI constrains (coming from function 1 of the Low Power S0 Idle _DSM interface) is not power-manageable via ACPI (no _PS0 method and no power resources), the code generating diagnostic information for the LPI constraints will print a message about that to the kernel log on every system suspend-resume cycle (possibly for multiple times). That is not very useful and noisy, so modify that code to disregard the LPI list entries corresponding to the devices that are not power- manageable after printing that information for them once.

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.
