Re: [PATCH v2] ASoC: loongson: Fix invalid position error in ls_pcm_pointer

[lijun]

for example,the DMA controller is abnormal in hardware
the addr = 0,
addr = ((u64)desc->saddr_hi << 32) | desc->saddr;
x = bytes_to_frames(runtime, addr - runtime->dma_addr);
addr = 0 dma_addr=4195352576   x=-1048838144 i think the value of pos 
should not be a negative，return 0, maybe better.
