[PATCH v5 14/16] staging: mt7621-pci: remove remaining pci_legacy dependant code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



pcibios_* remaining code is not neccessary at all. We are mapping
irq using of_irq_parse_and_map_pci and swizzle_irq which are set
in driver 'probe' function. Remove this code. No kernel config
option CONFIG_PCI_DRIVERS_LEGACY should be included anymore.
