Christophe JAILLET 7a77379fe1 media: cx23885: switch from 'pci_' to 'dma_' API 
The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'cx23885_risc_buffer()' GFP_KERNEL can be used
because this function is only called from a vb2_ops buf_prepare function.
The call chain is:
  cx23885_video_qops.buf_prepare        (cx23885-video.c)
    --> buffer_prepare                  (cx23885-video.c)
      --> cx23885_risc_buffer

When memory is allocated in 'cx23885_risc_databuffer()' GFP_KERNEL can be
used because this function is only called from a function that already uses
GFP_KERNEL or from a vb2_ops buf_prepare
function.
The call chains are:
  snd_cx23885_hw_params                 (cx23885-alsa.c) --> use GFP_KERNEL
    --> cx23885_risc_databuffer

  cx23885_qops.buffer_prepare           (cx23885-417.c)
     or
  dvb_qops.buffer_prepare               (cx23885-dvb.c)
    --> cx23885_buf_prepare
      --> cx23885_risc_databuffer

When memory is allocated in 'cx23885_risc_vbibuffer()' GFP_KERNEL can be
used because this function is only called from a vb2_ops buf_prepare
function.
The call chains are:
  cx23885_vbi_qops.buffer_prepare       (cx23885-vbi.c)
    --> cx23885_risc_vbibuffer
