From 3bd0c69653ac636eae8872aacdcd4156f772f928 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 23 May 2022 16:32:58 +0200 Subject: [PATCH] ath11k: fix IRQ affinity warning on shutdown Make sure to clear the IRQ affinity hint also on shutdown to avoid triggering a WARN_ON_ONCE() in __free_irq() when stopping MHI while using a single MSI vector.
