From bed0adac1ded4cb486ba19a3a7e730fbd9a1c9c6 Mon Sep 17 00:00:00 2001 From: Sireesh Kodali Date: Thu, 26 May 2022 19:47:39 +0530 Subject: [PATCH] remoteproc: qcom: wcnss: Fix handling of IRQs The wcnss_get_irq function is expected to return a value > 0 in the event that an IRQ is succssfully obtained, but it instead returns 0. This causes the stop and ready IRQs to never actually be used despite being defined in the device-tree. This patch fixes that.
