From 4e2e4ea0d8029874ef7d8f326e91c6ec6993a1bf Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Fri, 11 Oct 2024 12:04:39 +0800 Subject: [PATCH] um: hostaudio: Do not propagate dsp 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.
