From 3f48113df3495540fb492760dfb092deaccc9f7d Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Fri, 11 Oct 2024 12:04:40 +0800 Subject: [PATCH] um: hostaudio: Do not propagate mixer parameter to kernel This parameter is UML specific and is unknown to kernel. It should not be propagated to kernel, otherwise it will trigger a warning and be passed to user space as an environment option.
