Subject: [PATCH] ASoC: qcom: Add checks for devm_kcalloc
Git-commit: 1bf5ee979076ceb121ee51c95197d890b1cee7f4
Patch-mainline: v6.2-rc1
References: git-fixes

As the devm_kcalloc may return NULL, the return value needs to be checked
to avoid NULL poineter dereference.

Fixes: 24caf8d9eb10 ("ASoC: qcom: lpass-sc7180: Add platform driver for lpass audio")
