Merge tag 'for-v6.4-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
Pull power supply fixes from Sebastian Reichel: - Fix power_supply_get_battery_info for devices without parent devices resulting in NULL pointer dereference - Fix desktop systems reporting to run on battery once a power-supply device with device scope appears (e.g. a HID keyboard with a battery) - Ratelimit debug print about driver not providing data - Fix race condition related to external_power_changed in multiple drivers (ab8500, axp288, bq25890, sc27xx, bq27xxx) - Fix LED trigger switching from blinking to solid-on when charging finishes - Fix multiple races in bq27xxx battery driver - mt6360: handle potential ENOMEM from devm_work_autocancel - sbs-charger: Fix SBS_CHARGER_STATUS_CHARGE_INHIBITED bit - rt9467: avoid passing 0 to dev_err_probe * tag 'for-v6.4-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply: (21 commits) power: supply: Fix logic checking if system is running from battery power: supply: mt6360: add a check of devm_work_autocancel in mt6360_charger_probe power: supply: sbs-charger: Fix INHIBITED bit for Status reg power: supply: rt9467: Fix passing zero to 'dev_err_probe' power: supply: Ratelimit no data debug output power: supply: Fix power_supply_get_battery_info() if parent is NULL power: supply: bq24190: Call power_supply_changed() after updating input current power: supply: bq25890: Call power_supply_changed() after updating input current or voltage power: supply: bq27xxx: Use mod_delayed_work() instead of cancel() + schedule() power: supply: bq27xxx: After charger plug in/out wait 0.5s for things to stabilize power: supply: bq27xxx: Ensure power_supply_changed() is called on current sign changes power: supply: bq27xxx: Move bq27xxx_battery_update() down power: supply: bq27xxx: Add cache parameter to bq27xxx_battery_current_and_status() power: supply: bq27xxx: Fix poll_interval handling and races on remove power: supply: bq27xxx: Fix I2C IRQ race on remove power: supply: bq27xxx: Fix bq27xxx_battery_update() race condition power: supply: leds: Fix blink to LED on transition power: supply: sc27xx: Fix external_power_changed race power: supply: bq25890: Fix external_power_changed race power: supply: axp288_fuel_gauge: Fix external_power_changed race ...
