[PATCH] include/asm-generic/pci.h: include generic "pci-dma-compat.h"

[Chen Gang]

If an architecture need "generic pci.h", it also need generic "pci-dma-
compat.h",  so recommend to include it in asm-generic directly.

And now, for arm64 and m32r, may cause compiling error about it.

The related error (with allmodconfig):

  drivers/media/usb/b2c2/flexcop-usb.c: In function ?flexcop_usb_transfer_exit?:
  drivers/media/usb/b2c2/flexcop-usb.c:393:3: error: implicit declaration of function ?pci_free_consistent? [-Werror=implicit-function-declaration]

  drivers/media/usb/b2c2/flexcop-usb.c:410:21: warning: assignment makes pointer from integer without a cast [enabled by default]
  cc1: some warnings being treated as errors

(but make sure it doesn't break other archs)

Thanks.

I will try to check all related archs with allmodconfig (which can also
find more another patches, and can let me familiar the compiler step by
step).  ;-)


Thanks.
