Subject: [PATCH AUTOSEL for 4.9 030/156] irqchip/mvebu-odmi: Select
 GENERIC_MSI_IRQ_DOMAIN

From: Arnd Bergmann <arnd@...db.de>

[ 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.
