UPSTREAM: ASoC: soc-pcm: use GFP_ATOMIC for dpcm structure

Browse Source 
[ Upstream commit d8a9c6e1f6766a16cf02b4e99a629f3c5512c183 ]

We allocate a structure in dpcm_be_connect(), which may be called in
atomic context. Using GFP_KERNEL is not quite right, we have to use
GFP_ATOMIC to prevent the allocator from sleeping.
