This is a note to let you know that I've just added the patch titled power: supply: bq25890: Ensure pump_express_work is cancelled on remove to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: power-supply-bq25890-ensure-pump_express_work-is-can.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9a79acfe37090792e7a7aa7d04f662e1894e1368 Author: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Mon Nov 28 10:28:48 2022 +0100 power: supply: bq25890: Ensure pump_express_work is cancelled on remove [ Upstream commit a7aaa80098d5b7608b2dc1e883e3c3f929415243 ] The pump_express_work which gets queued from an external_power_changed callback might be pending / running on remove() (or on probe failure). Add a devm action cancelling the work, to ensure that it is cancelled. Note the devm action is added before devm_power_supply_register(), making it run after devm unregisters the power_supply, so that the work cannot be queued anymore (this is also why a devm action is used for this).
