Subject: [PATCH] ASoC: acp: check the return value of devm_kzalloc() in acp_legacy_dai_links_create()
Git-commit: 431f9a77a4a62694ce90742d1f4c5abe1b8b6612
Patch-mainline: v5.18-rc1
References: jsc#PED-850
The function devm_kzalloc() in acp_legacy_dai_links_create() can fail,
so its return value should be checked.
