If anyone has any objections, please let me know. ------------------ From: Myeonghun Pak commit 08b2ccd7eb7e41f77a04a09112ca3edcc588e3f0 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.
