Subject: [PATCH] PCI: dwc: exynos: add back MSI dependency
Date: Fri,  4 Dec 2020 17:58:34 +0100	[thread overview]
Message-ID: <20201204165841.3845589-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

While the exynos driver does not always need MSI, the generic
deisgnware host code it uses fails to build without it:

WARNING: unmet direct dependencies detected for PCIE_DW_HOST
  Depends on [n]: PCI [=y] && PCI_MSI_IRQ_DOMAIN [=n]
  Selected by [y]:
  - PCI_EXYNOS [=y] && PCI [=y] && (ARCH_EXYNOS [=n] || COMPILE_TEST [=y])
drivers/pci/controller/dwc/pcie-designware-host.c:247:19: error: implicit declaration of function 'pci_msi_create_irq_domain' [-Werror,-Wimplicit-function-declaration]
        pp->msi_domain = pci_msi_create_irq_domain(fwnode,
                         ^

Add back the dependency that all other designware controllers have.
