Date: Mon, 9 Mar 2020 18:18:45 +0000 From: Andre Przywara <andre.przywara@....com> To: "David S . Miller" <davem@...emloft.net>, Radhey Shyam Pandey <radhey.shyam.pandey@...inx.com> Cc: Michal Simek <michal.simek@...inx.com>, Robert Hancock <hancock@...systems.ca>, netdev@...r.kernel.org, rmk+kernel@....linux.org.uk, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Andrew Lunn <andrew@...n.ch> Subject: [PATCH v2 08/14] net: axienet: Mark eth_irq as optional 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.
