From 640803003cd903cea73dc6a86bf6963e238e2b3f Mon Sep 17 00:00:00 2001 From: Jorge Ramirez-Ortiz jorge.ramirez@oss.qualcomm.com Date: Thu, 19 Jun 2025 09:48:30 +0200 Subject: [PATCH] media: venus: hfi: explicitly release IRQ during teardown
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.
