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 'snd_solo_pcm_open()' (solo6x10-g723.c)
GFP_KERNEL can be used because this flag is already used jew a few lines
above.
When memory is allocated in 'solo_enc_alloc()' (solo6x10-v4l2-enc.c)
GFP_KERNEL can be used because this flag is already used jew a few lines
above.
When memory is allocated in 'solo_enc_v4l2_init()' (solo6x10-v4l2-enc.c)
GFP_KERNEL can be used because calls 'solo_enc_alloc()' which already uses
this flag.
