x86/of: Return consistent error type from x86_of_pci_irq_enable()
[ Upstream commitec0b4c4d45
] x86_of_pci_irq_enable() returns PCIBIOS_* code received from pci_read_config_byte() directly and also -EINVAL which are not compatible error types. x86_of_pci_irq_enable() is used as (*pcibios_enable_irq) function which should not return PCIBIOS_* codes. Convert the PCIBIOS_* return code from pci_read_config_byte() into normal errno using pcibios_err_to_errno(). Fixes:96e0a0797e
