[RFC PATCH 01/11] drivers: acpi: iort: fix struct pci_dev compiler warnings

Show all headers | View raw

When the kernel is configured with no IORT support the compilation
issues the following warnings:

In file included from drivers/irqchip/irq-gic-v3-its-pci-msi.c:19:0:
include/linux/iort.h:28:33: warning: 'struct pci_dev' declared inside
parameter list
 u32 iort_pci_get_msi_rid(struct pci_dev *pdev, u32 req_id);
                                 ^
include/linux/iort.h:28:33: warning: its scope is only this definition
or declaration, which is probably not what you want
include/linux/iort.h:29:50: warning: 'struct pci_dev' declared inside
parameter list
 struct fwnode_handle *iort_pci_get_domain(struct pci_dev *pdev, u32
req_id);

This patch fixes the warnings with a struct pci_dev forward declaration
in the IORT header file.
