Subject: [PATCH 1/2] iommu/riscv: Free irq vectors on pci remove
Date: Wed,  6 Nov 2024 18:51:04 +0100	[thread overview]
Message-ID: <20241106175102.219923-5-ajones@ventanamicro.com> (raw)
In-Reply-To: <20241106175102.219923-4-ajones@ventanamicro.com>

riscv_iommu_pci_probe() calls pci_alloc_irq_vectors() which
states pci_free_irq_vectors() must be called on cleanup.

Fixes: 68682e9578fb ("iommu/riscv: Add RISC-V IOMMU PCIe device driver")
