From: Srinivas Kandagatla Date: Tue, 9 Sep 2025 12:19:42 +0000 (+0100) Subject: ASoC: codecs: wcd937x: set the comp soundwire port correctly X-Git-Tag: v6.12.53~33 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=abcd537aae3b84c6d10ad147e99a204bcb56b234;p=thirdparty%2Fkernel%2Fstable.git ASoC: codecs: wcd937x: set the comp soundwire port correctly commit 66a940b1bf48a7095162688332d725ba160154eb upstream. For some reason we endup with setting soundwire port for HPHL_COMP and HPHR_COMP as zero, this can potentially result in a memory corruption due to accessing and setting -1 th element of port_map array.
