From 9503a1fc123d9c9c502a7e518634296874a7b8cc Mon Sep 17 00:00:00 2001 From: Minghao Chi Date: Mon, 14 Mar 2022 06:45:01 +0000 Subject: [PATCH] ath9k: Use platform_get_irq() to get the interrupt MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ) for requesting IRQ's resources any more, as they can be not ready yet in case of DT-booting. platform_get_irq() instead is a recommended way for getting IRQ even if it was not retrieved earlier. It also makes code simpler because we're getting "int" value right away and no conversion from resource to int is required.
