Subject: [patch V2 27/40] irqchip/mbigen: Remove platform_msi_create_device_domain() fallback
Date: Mon, 21 Nov 2022 15:40:02 +0100 (CET) [thread overview]
Message-ID: <20221121140050.005249847@linutronix.de> (raw)
In-Reply-To: 20221121135653.208611233@linutronix.de
Now that ITS provides the MSI parent domain, remove the unused fallback
code.
