[PATCH tip/core/rcu 11/13] rcutorture: Eliminate unused ts_rem local from rcu_trace_clock_local()

Show all headers | View raw

This commit removes an unused local variable named ts_rem that is
marked __maybe_unused.  Yes, the variable was assigned to, but it
was never used beyond that point, hence not needed.
