Wysocki The intel-hid driver is missing a PM ->thaw callback allowing the device to go back to the operational state after creating a hibernation image or when there is an image restoration error during resume. The lack of the ->thaw callback basically means that all events signaled by the device are discarded after a hibernation image has been created which may be problematic, for example, if the image cannot be saved (eg. due to an I/O issue with storage).
