Subject: [PATCH v3 08/14] net: axienet: Mark eth_irq as optional
Date: Tue, 24 Mar 2020 13:23:41 +0000	[thread overview]
Message-ID: <20200324132347.23709-9-andre.przywara@arm.com> (raw)
In-Reply-To: <20200324132347.23709-1-andre.przywara@arm.com>

According to the DT binding, the Ethernet core interrupt is optional.

Use platform_get_irq_optional() to avoid the error message when the
IRQ is not specified.
