[PATCH v3] sparc/PCI: Use dev_is_pci() to identify PCI devices

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

 



Use dev_is_pci() instead of checking bus type directly.

v2->v3: Keep use dev->bus == &pci_bus_type in 
        arch/sparc/include/asm/dma-mapping.h, because we
		can't include <linux/pci.h> in this file, or it will
		cause lots of building errors, it's so strange. 
		This patch was built ok in my Cross Complier.
