power: reset: st-poweroff: Use of_device_get_match_data()

2026-06-03T20:56:42+00:00

Use of_device_get_match_data() to fetch the reset syscfg data directly instead of open-coding an of_match_device() lookup. This also lets the driver drop the of_device.h include.

power: reset: linkstation-poweroff: fix use-after-free in the linkstation_poweroff_init()

2026-06-03T19:58:00+00:00

Move of_node_put(dn) after the of_match_node() call, which still needs the node pointer. The node reference is correctly released after use.

power: reset: sc27xx: Add platform_device_id table

2026-06-01T23:37:00+00:00

Make the poweroff driver for SC27xx-series PMICs probe automatically. Since the device representing the poweroff functionality of the SC27xx PMIC is not supposed to have a dedicated device tree node without any corresponding DT resources [1], an of_device_id table cannot be used here. Instead, use a platform_device_id table to match the poweroff sub-device instantiated by the parent MFD driver.

power: Use named initializers for platform_device_id arrays

2026-06-01T23:34:21+00:00

Named initializers are better readable and more robust to changes of the struct definition. This robustness is relevant for a planned change to struct platform_device_id replacing .driver_data by an anonymous union. While touching these arrays unify spacing and usage of commas.

power: Drop unused assignment of platform_device_id driver data

2026-06-01T23:34:21+00:00

The driver explicitly set the .driver_data member of struct platform_device_id to zero without relying on that value. Drop this unused assignments. While touching this array unify spacing, use a named initializer for .name and drop trailing commas after the list terminators.

power: reset: Add QEMU virt-ctrl driver

2026-04-13T10:16:10+00:00

Add a new driver for the 'virt-ctrl' device found on QEMU virt machines (e.g. m68k). This device provides a simple interface for system reset and power off [1]. This driver utilizes the modern system-off API to register callbacks for both system restart and power off. It also registers a reboot notifier to catch SYS_HALT events, ensuring that LINUX_REBOOT_CMD_HALT is properly handled. It is designed to be generic and can be reused by other architectures utilizing this QEMU device.

power: reset: drop unneeded dependencies on OF_GPIO

2026-04-02T22:40:09+00:00

OF_GPIO is selected automatically on all OF systems. Any symbols it controls also provide stubs so there's really no reason to select it explicitly. For Kconfig entries that have no other dependencies: convert it to requiring OF to avoid new symbols popping up for everyone in make config, for others just drop it altogether.

power: reset: reboot-mode: fix -Wformat-security warning

2026-03-11T06:58:43+00:00

The device_create() function expects a format string to construct a device name, so passing a variable here introduces a possible vulnerability in case the string can contain '%' characters: drivers/power/reset/reboot-mode.c:148:22: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security] drivers/power/reset/reboot-mode.c:148:22: note: treat the string as an argument to avoid this 148 | (void *)priv, reboot->dev->driver->name); Use an trivial "%s" format instead and pass the name as the string to be included here.
