acpi_get_object_info() is intended for early probe usage and as such should not call any methods which may rely on OpRegions, but it used to also call _STA to get the status, which on some systems does rely on OpRegions, this behavior and the acpi_device_info.current_status member are being removed. This commit prepares the acpiphp_ibm code for this by having it get the status itself using acpi_bus_get_status_handle(). Note no error handling is necessary on any errors acpi_bus_get_status_handle() leaves the value of the passed in current_status at its 0 initialization value.

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.
