Subject: ftrace-graph: Remove usage of ftrace_stop() in ftrace_graph_stop()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=545d47b8f359f7e9b5beabc28bfeecb3fc6af1ee;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ftrace-graph: Remove usage of ftrace_stop() in ftrace_graph_stop()

All archs now use ftrace_graph_is_dead() to stop function graph
tracing. Remove the usage of ftrace_stop() as that is no longer
needed.
