[PATCH] x86/pci: Add missing forward declaration for pci_numachip_init()

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

 



At the moment, the function pci_numachip_init() is defined in the
numachip.c file.  Since this function has users outside of this file,
add missing foward declaration to the pci_x86.h file.

This resolves the following sparse and compile time warning:

  arch/x86/pci/numachip.c:108:12: warning: no previous prototype for function 'pci_numachip_init' [-Wmissing-prototypes]
  arch/x86/pci/numachip.c:108:12: warning: symbol 'pci_numachip_init' was not declared. Should it be static?
