snd_dma_alloc_pages_fallback - allocate the buffer area according to
the given type with fallback
int snd_dma_alloc_pages_fallback (int type, struct device * device,
struct snd_dma_buffer * dmab);
type the DMA buffer type
device the device pointer
size the buffer size to allocate
dmab buffer allocation record to store the allocated data
Calls the memory-allocator function for the corresponding buffer type.
When no space is left, this function reduces the size and tries to
allocate again. The size actually allocated is stored in res_size
Returns zero if the buffer with the given size is allocated
successfuly, other a negative value at error.
