[for-next][PATCH 10/10] tracing: Use atomic64_inc_return() in trace_clock_counter()

[Steven Rostedt]

From: Uros Bizjak <ubizjak@xxxxxxxxx>

Use atomic64_inc_return(&ref) instead of atomic64_add_return(1, &ref)
to use optimized implementation and ease register pressure around
the primitive for targets that implement optimized variant.
