If anyone has any objections, please let me know. ------------------ From: Myeonghun Pak commit b1b0f8bdbbc891a4ee7f3b1a878c633e02b7bbeb upstream. Probe enables controller wakeup after the OHCI core marks controllers with RemoteWakeupConnected as wakeup-capable. Removal does not undo this, so the wakeup source can remain attached after driver unbind. Disable controller wakeup after removing the HCD. This issue was identified during our ongoing static-analysis research while reviewing kernel code.
