4.14-stable review patch. If anyone has any objections, please let me know.

commit a1ab69021a584d952e6548a44b93760547b1b6b5 upstream.
We want to free memory reserved for interrupt mask handling only after we free functions, as function drivers might want to mask interrupts. This is needed for the followup patch to the F03 that would implement unmasking and masking interrupts from the serio pass-through port open() and close() methods.
