From 5bf4b20dc19090fef115f20d63d0adc6267d2928 Mon Sep 17 00:00:00 2001 From: Minghao Chi Date: Wed, 9 Mar 2022 05:36:11 +0000 Subject: [PATCH] usb:oxu210hp-hcd: Use platform_get_irq() to get the interrupt 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.
