[ Upstream commit fa23b9d1b89fdc34f296f02e496a20aeff5736be ]

This driver uses the MSI domain but has no strict dependency on PCI_MSI, so we may run into a build failure when CONFIG_GENERIC_MSI_IRQ_DOMAIN is disabled:

drivers/irqchip/irq-mvebu-odmi.c:152:15: error: variable 'odmi_msi_ops' has initializer but incomplete type static struct msi_domain_ops odmi_msi_ops = { ^~~~~~~~~~~~~~ drivers/irqchip/irq-mvebu-odmi.c:155:15: error: variable 'odmi_msi_domain_info' has initializer but incomplete type static struct msi_domain_info odmi_msi_domain_info = { ^~~~~~~~~~~~~~~ drivers/irqchip/irq-mvebu-odmi.c:156:3: error: 'struct msi_domain_info' has no member named 'flags' .flags = (MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS), ^~~~~ drivers/irqchip/irq-mvebu-odmi.c:156:12: error: 'MSI_FLAG_USE_DEF_DOM_OPS' undeclared here (not in a function) .flags = (MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS), ^~~~~~~~~~~~~~~~~~~~~~~~ drivers/irqchip/irq-mvebu-odmi.c:156:39: error: 'MSI_FLAG_USE_DEF_CHIP_OPS' undeclared here (not in a function); did you mean 'MSI_FLAG_USE_DEF_DOM_OPS'?

Selecting the option from this driver seems to solve this nicely, though I could not find any other instance of this in irqchip drivers.
