mm: drop useless local parameters of __register_one_node()

2017-07-10T23:32:32+00:00

__register_one_node() initializes local parameters "p_node" & "parent" for register_node(). But, register_node() does not use them. Remove the related code of "parent" node, cleanup __register_one_node() and register_node().

Pull device properties framework updates from Rafael Wysocki: "These mostly rearrange the device properties core code and add a few helper functions to it as a foundation for future work. Specifics: - Rearrange the core device properties code by moving the code specific to each supported platform configuration framework (ACPI, DT and build-in) into a separate file (Sakari Ailus). - Add helper functions for accessing device properties in a firmware-agnostic way (Sakari Ailus, Kieran Bingham)" * tag 'devprop-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: device property: Add fwnode_graph_get_port_parent device property: Add FW type agnostic fwnode_graph_get_remote_node device property: Introduce fwnode_device_is_available() device property: Move fwnode graph ops to firmware specific locations device property: Move FW type specific functionality to FW specific files ACPI: Constify argument to acpi_device_is_present()

Merge tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

2017-07-07T19:40:27+00:00

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.13 series. Some administrativa: I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO driver coming in through this tree, along with a whole bunch of Exar 8250 fixes. These are ACKed by Greg and also hit drivers/platform/* where they are ACKed by Andy Shevchenko. Speaking about drivers/platform/* there is also a bunch of ACPI stuff coming through that route, again ACKed by Andy. The MCP23S08 changes are coming in here as well. You already have the commits in your tree, so this is just a result of sharing an immutable branch between pin control and GPIO. Core: - Export add/remove for lookup tables so that modules can export GPIO descriptor tables. - Handle GPIO sleep states: it is now possible to flag that a GPIO line may loose its state during suspend/resume of the system to save power. This is used in the Wolfson Micro Arizona driver. - ACPI-based GPIO was tightened up a lot around the edges. - Use bitmap_fill() to speed up a loop. New drivers: - Exar XRA1403 SPI-based GPIO. - MVEBU driver now supports Armada 7K and 8K. - LP87565 PMIC GPIO. - Renesas R-CAR R8A7743 (RZ/G1M). - The new IOT2040 8250 serial/GPIO also comes in through this changeset. Substantial driver changes: - Seriously fix the Exar 8250 GPIO portions to work. - The MCP23S08 was moved out to a pin control driver. - Convert MEVEBU to use regmap for register access. - Drop Vulcan support from the Broadcom driver. - Serious cleanup and improvement of the mockup driver, giving us a better test coverage. Misc: - Lots of janitorial clean up. - A bunch of documentation fixes" * tag 'gpio-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (70 commits) serial: exar: Add support for IOT2040 device gpio-exar/8250-exar: Make set of exported GPIOs configurable platform: Accept const properties serial: exar: Factor out platform hooks gpio-exar/8250-exar: Rearrange gpiochip parenthood gpio: exar: Fix iomap request gpio-exar/8250-exar: Do not even instantiate a GPIO device for Commtech cards serial: uapi: Add support for bus termination gpio: rcar: Add R8A7743 (RZ/G1M) support gpio: gpio-wcove: Fix GPIO control register offset calculation gpio: lp87565: Add support for GPIO gpio: dwapb: fix missing first irq for edgeboth irq type MAINTAINERS: Take maintainership for GPIO ACPI support gpio: exar: Fix reading of directions and values gpio: exar: Allocate resources on behalf of the platform device gpio-exar/8250-exar: Fix passing in of parent PCI device gpio: mockup: use devm_kcalloc() where applicable gpio: mockup: add myself as author gpio: mockup: improve the error message gpio: mockup: don't return magic numbers from probe() ...

Add "shutdown" to "struct class".

The TPM class has some common shutdown code that must be executed for all drivers. This adds some needed functionality for that.
