Subject: [PATCH] pinctrl: bcm2835: Accept fewer than expected IRQs
Date: Fri, 21 May 2021 12:01:58 +0300	[thread overview]
Message-ID: <20210521090158.26932-1-iivanov@suse.de> (raw)

From: Phil Elwell <phil@raspberrypi.com>

The downstream .dts files only request two GPIO IRQs. Truncate the
array of parent IRQs when irq_of_parse_and_map returns 0.
