Maximilian Luz dc0393c76f platform/surface: aggregator: Allow devices to be marked as hot-removed ... Some SSAM devices, notably the keyboard cover (keyboard and touchpad) on the Surface Pro 8, can be hot-removed. When this occurs, communication with the device may fail and time out. This timeout can unnecessarily block and slow down device removal and even cause issues when the devices are detached and re-attached quickly. Thus, communication should generally be avoided once hot-removal is detected. While we already remove a device as soon as we detect its (hot-)removal, the corresponding device driver may still attempt to communicate with the device during teardown. This is especially critical as communication failure may also extend to disabling of events, which is typically done at that stage. Add a flag to allow marking devices as hot-removed. This can then be used during client driver teardown to check if any communication attempts should be avoided.
