From bf2b83425b599d897e64a2509388f16da2ce6fd4 Mon Sep 17 00:00:00 2001 From: Minghao Chi Date: Thu, 10 Mar 2022 06:20:35 +0000 Subject: [PATCH] net: mv643xx_eth: use platform_get_irq() instead of platform_get_resource() 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. Reported-by: Zeal Robot Signed-off-by: Minghao Chi Signed-off-by: David S.
