If anyone has any objections, please let me know. ------------------ From: Ilpo Järvinen [ Upstream commit ec0b4c4d45cf7cf9a6c9626a494a89cb1ae7c645 ] 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().
