Summary

In the Linux kernel, the following vulnerability has been resolved:

HID: Add HID_CLAIMED_INPUT guards in raw_event callbacks missing them

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.
