From d8a9c6e1f6766a16cf02b4e99a629f3c5512c183 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Tue, 7 Dec 2021 11:37:40 -0600 Subject: [PATCH] ASoC: soc-pcm: use GFP_ATOMIC for dpcm structure 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.
