From 8226db2309e20928d04b33707289f82c00ca71ed Mon Sep 17 00:00:00 2001 From: Jorge Ramirez-Ortiz Date: Fri, 22 Aug 2025 23:41:51 -0400 Subject: [PATCH] media: venus: hfi: explicitly release IRQ during teardown [ Upstream commit 640803003cd903cea73dc6a86bf6963e238e2b3f ] 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.
