Subject: rcutorture: Eliminate unused ts_rem local from rcu_trace_clock_local()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a3b7b6c2739caf996b95a0164b5b4541c27630c3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

rcutorture: Eliminate unused ts_rem local from rcu_trace_clock_local()

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.
