From f117276638b7600b981b3fe28550823cfbe1ef23 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Wed, 1 Feb 2023 08:54:42 -0800 Subject: [PATCH] wifi: ath11k: Use platform_get_irq() to get the interrupt As of commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core"), we need to use platform_get_irq() instead of platform_get_resource() to get our IRQs because platform_get_resource() simply won't get them anymore. This was already fixed in several other Atheros WiFi drivers, apparently in response to Zeal Robot reports. An example of another fix is commit 9503a1fc123d ("ath9k: Use platform_get_irq() to get the interrupt"). ath11k seems to have been missed in this effort, though. Without this change, WiFi wasn't coming up on my Qualcomm sc7280-based hardware. Specifically, "platform_get_resource(pdev, IORESOURCE_IRQ, i)" was failing even for i=0.
