Hi!
From: Wang Kefeng wangkefeng.wang@huawei.com
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.
AFAICT this does not fix any bug. It is simply a WARN that can not trigger.
Best regards, Pavel
