    Subject[PATCH 5.14 039/100] tools/bootconfig: Fix tracing_on option checking in ftrace2bconf.sh
    Date
    From: Masami Hiramatsu <mhiramat@kernel.org>

    [ Upstream commit 32ba9f0fb027cc43074e3ea26fcf831adeee8e03 ]

    Since tracing_on indicates only "1" (default) or "0", ftrace2bconf.sh
    only need to check the value is "0".
