If anyone has any objections, please let me know. ------------------ From: Greg Kroah-Hartman commit ecfa6f34492c493a9a1dc2900f3edeb01c79946b upstream. In commit 2ff5baa9b527 ("HID: appleir: Fix potential NULL dereference at raw event handle"), we handle the fact that raw event callbacks can happen even for a HID device that has not been "claimed" causing a crash if a broken device were attempted to be connected to the system. Fix up the remaining in-tree HID drivers that forgot to add this same check to resolve the same issue.
