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.
Returns zero if the buffer with the given size is allocated
successfuly, other a negative value at error.
