From 92f774395fbca11d8e96347316663033e2cf260a Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Wed, 28 Oct 2020 14:20:01 +0000 Subject: ASoC: qcom: sm8250: Fix array out of bounds access Static analysis Coverity had detected a potential array out-of-bounds write issue due to the fact that MAX AFE port Id was set to 16 instead of using AFE_PORT_MAX macro. Fix this by properly using AFE_PORT_MAX macro.
