From: Vijendar Mukunda Date: Tue, 6 May 2025 12:07:23 +0000 (+0530) Subject: ASoC: amd: sof_amd_sdw: Fix unlikely uninitialized variable use in create_sdw_dailinks() X-Git-Tag: v6.12.35~403 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=082b0ca9a79d7d0f3669fc69e22a4af9ff10b07a;p=thirdparty%2Fkernel%2Fstable.git ASoC: amd: sof_amd_sdw: Fix unlikely uninitialized variable use in create_sdw_dailinks() commit 6b83ba4bc3ecb915476d688c9f00f3be57b49a0c upstream. Initialize current_be_id to 0 in SOF based AMD generic SoundWire machine driver to handle the unlikely case when there are no devices connected to a DAI. In this case create_sdw_dailink() would return without touching the passed pointer to current_be_id.
