If anyone has any objections, please let me know. ------------------ From: Shuangpeng Bai commit 43ae2f90b70cda374c487c1639a01d0f14e5d583 upstream. usb_power_delivery_find() wraps class_find_device_by_name(). That helper returns a device reference that must be released by the caller. select_usb_power_delivery_store() only needs this reference while calling the pd_set callback. Drop it once the callback returns. Otherwise the sysfs write can pin the selected USB Power Delivery object and prevent it from being released on unregister.
