From 7df92384c86f36d0452e7abad21c7eaa91aeeef7 Mon Sep 17 00:00:00 2001 From: Jiaxin Yu Date: Tue, 26 Jul 2022 23:31:30 +0800 Subject: ASoC: mediatek: mt8186: set the correct string to strncmp() Fix Smatch static checker warning. strncmp() here only needs to compare the first seven bytes, so in order to make the code more clear, only the first seven bytes of the string used as the comparison are reserved.
