Subjectlinux-next: build failure after merge of the driver-core tree
Hi all,

After merging the driver-core tree, today's linux-next build (sparc64
defconfig) failed like this:

drivers/of/property.o: In function `parse_interrupts':
property.c:(.text+0x14e0): undefined reference to `of_irq_parse_one'

Caused by commit

f265f06af194 ("of: property: Fix fw_devlink handling of interrupts/interrupts-extended")

CONFIG_OF_IRQ depends on !SPARC so of_irq_parse_one() needs a stub.
I have added the following patch for today.

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Wed, 10 Feb 2021 21:27:56 +1100
Subject: [PATCH] of: irq: make a stub for of_irq_parse_one()
