Subject: drivers/hwtracing/intel_th/msu.c: change return type to vm_fault_t
Use new return type vm_fault_t for fault handler. For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno. Once all instances are converted, vm_fault_t will become a
distinct type.
See 1c8f422059ae ("mm: change return type to vm_fault_t") for reference.
