From 57f31b313231d81639813eac0a3c2e21984bf557 Mon Sep 17 00:00:00 2001 From: Wang Kefeng Date: Mon, 23 Aug 2021 10:41:42 +0100 Subject: [PATCH] ARM: 9120/1: Revert "amba: make use of -1 IRQs warn" commit eb4f756915875b0ea0757751cd29841f0504d547 upstream. After commit 77a7300abad7 ("of/irq: Get rid of NO_IRQ usage"), no irq case has been removed, irq_of_parse_and_map() will return 0 in all cases when get error from parse and map an interrupt into linux virq space. amba_device_register() is only used on no-DT initialization, see s3c64xx_pl080_init() arch/arm/mach-s3c/pl080.c ep93xx_init_devices() arch/arm/mach-ep93xx/core.c They won't set -1 to irq[0], so no need the warn. This reverts commit 2eac58d5026e4ec8b17ff8b62877fea9e1d2f1b3.
