The ACPI battery driver already uses devm_kzalloc() for allocating memory and devm_mutex_init() for mutex initialization, but it still carries out some manual rollback in acpi_battery_probe(). Switch it over to devres-based resource management completely by making three changes: * Rename acpi_battery_update_retry() to devm_acpi_battery_update_retry(), turn sysfs_battery_cleanup() into a devm action and modify the former to add it. * Add devm_acpi_battery_init_wakeup() for initializing the wakeup source and make it add a custom devm action to automatically remove the wakeup source registered by it. * Make acpi_battery_probe() use devm_acpi_install_notify_handler() that has just been introduced for installing an ACPI notify handler. Note that the code ordering change related to the last of the above changes does not matter because there is no functional dependency between the PM notifier and the wakeup source or the ACPI notify handler. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Link: https://patch.msgid.link/10856906.nUPlyArG6x@rafael.j.wysocki
