From b6886c7826a17eaa908d7bae1537812bb78eb9fe Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 15 Dec 2021 16:53:57 -0600 Subject: [PATCH] usb: ohci-s3c2410: Use platform_get_irq() to get the interrupt Accessing platform device resources directly has long been deprecated for DT as IRQ resources may not be available at device creation time. Drivers relying on the static IRQ resources is blocking removing the static setup from the DT core code.
