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

From: Jorge Ramirez-Ortiz jorge.ramirez@oss.qualcomm.com
commit 640803003cd903cea73dc6a86bf6963e238e2b3f upstream.
Ensure the IRQ is disabled - and all pending handlers completed - before dismantling the interrupt routing and clearing related pointers.
This prevents any possibility of the interrupt triggering after the handler context has been invalidated.
