Subject: [PATCH 05/11] irqchip/riscv-imsic: Convert to msi_create_parent_irq_domain() helper
Date: Wed,  4 Dec 2024 12:45:43 +0000	[thread overview]
Message-ID: <20241204124549.607054-6-maz@kernel.org> (raw)
In-Reply-To: <20241204124549.607054-1-maz@kernel.org>

Now that we have a concise helper to create an MSI parent domain,
switch the RISC-V letter soup over to that.
