That drops the last reference, so the device's\nrelease callback i3c_device_release() runs and frees the i3c_device.\n\nTwo problems follow from that:\n\ni3c_device_release() does WARN_ON(i3cdev->desc), so it warns because\ndesc->dev->desc still points back at the descriptor.  Clear it before\ncalling put_device().\n\nAfter put_device() frees the i3c_device, desc->dev is left pointing at\nfreed memory, so clear desc->dev as well.  That prevents, for example,\ni3c_master_unregister_i3c_devs() seeing desc->dev as non-NULL and\ndereferencing it."
