latencytop: Deprecate tracing_enabled for tracing_on
tracing_enabled should not be used, it is heavy weight and does not do much in helping lower the overhead. see commmit (Deprecate tracing_enabled for tracing_on 6752ab4a9c30d5411b2dfdb251a3f1cb18aae48) in kernel (From OE-Core rev: ee95048cf0c79dc52857dbc0e5da9363f2ad8b9b) Signed-off-by: Roy.Li <rongqing.li@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

1linux: sysfs: use tracing_on as tracing_enabled is deprecated
2
3tracing_enabled use in the kernel is being deprecated as per commit
46752ab4a9c30 [tracing: Deprecate tracing_enabled for tracing_on] in
5the linux mainline kernel. tracing_enabled use will generate a warning
6and may no longer function as expected, therefore move to use tracing_on.
