Christophe JAILLET 00ae4ebc2d media: pci: cx88: 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.

Only 2 functions allocate some memory. They are both in cx88-core.c

When memory is allocated in 'cx88_risc_buffer()', GFP_KERNEL can be
used because its 2 callers end up to '.buf_prepare' functions in 'vb2_ops'
structures.
The call chains are:

  .buf_prepare                   (cx88-vbi.c)
    --> buffer_prepare           (cx88-vbi.c)
      --> cx88_risc_buffer

  .buf_prepare                   (cx88-video.c)
    --> buffer_prepare           (cx88-video.c)
      --> cx88_risc_buffer

When memory is allocated in 'cx88_risc_databuffer()', GFP_KERNEL can be
used because its 2 callers end up to 'snd_cx88_hw_params' which already
uses GFP_KERNEL and '.buf_prepare' functions in 'vb2_ops' structures.
The call chains are:

  snd_cx88_hw_params                   (cx88-alsa.c)
    --> cx88_risc_databuffer

  .buf_prepare                         (cx88-blackbird.c)
    --> buffer_prepare                 (cx88-blackbird.c)
      --> cx8802_buf_prepare           (cx88-mpeg.c)
        --> cx88_risc_databuffer

  .buf_prepare                         (cx88-dvb.c)
    --> buffer_prepare                 (cx88-dvb.c)
      --> cx8802_buf_prepare           (cx88-mpeg.c)
        --> cx88_risc_databuffer
