This means that during removal, there is a race\ncondition where an interrupt can fire just _after_ the `power_supply`\nhandle has been freed, *but* just _before_ the corresponding\nunregistration of the IRQ handler has run.\n\nThis will lead to the IRQ handler calling `power_supply_changed()` with\na freed `power_supply` handle. Which usually crashes the system or\notherwise silently corrupts the memory...\n\nNote that there is a similar situation which can also happen during\n`probe()`; the possibility of an interrupt firing _before_ registering\nthe `power_supply` handle. This would then lead to the nasty situation\nof using the `power_supply` handle *uninitialized* in\n`power_supply_changed()`.\n\nFix this racy use-after-free by making sure the IRQ is requested _after_\nthe registration of the `power_supply` handle."
