From f8b729ce97f66807f6b958e891888d0b1ed20a9e Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 14 Nov 2022 12:52:01 +0100 Subject: fotg210-udc: Get IRQ using platform_get_irq() The platform_get_irq() is necessary to use to get dynamic IRQ resolution when instantiating the device from the device tree. IRQs are not passed as resources in that case.
