Subject: [PATCH] tools/bootconfig: Fix tracing_on option checking in ftrace2bconf.sh
Git-commit: 32ba9f0fb027cc43074e3ea26fcf831adeee8e03
Patch-mainline: v5.15-rc1
References: stable-5.14.8
[ Upstream commit 32ba9f0fb027cc43074e3ea26fcf831adeee8e03 ]
Since tracing_on indicates only "1" (default) or "0", ftrace2bconf.sh
only need to check the value is "0".
