[PATCH 1/6] ASoC: soc-pcm: use GFP_ATOMIC for dpcm structure

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

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.
