NAME
       snd_dma_alloc_pages_fallback - allocate the buffer area according to the given type with fallback

SYNOPSIS
       int snd_dma_alloc_pages_fallback(int type, struct device * device, size_t size, struct snd_dma_buffer * dmab);

ARGUMENTS
       type
	   the DMA buffer type

       device
	   the device pointer

       size
	   the buffer size to allocate

       dmab
	   buffer allocation record to store the allocated data

DESCRIPTION
       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 argument.

RETURN
       Zero if the buffer with the given size is allocated successfully, otherwise a negative value on error.
