Subject: [PATCH] ASoC: soc-pcm: use GFP_ATOMIC for dpcm structure
Git-commit: d8a9c6e1f6766a16cf02b4e99a629f3c5512c183
Patch-mainline: v5.17-rc1
References: jsc#PED-850
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.
