[ Upstream commit 7867299cde34e9c2d2c676f2a384a9d5853b914d ] The condition should be skipped if CPU ID equal to nthreads. The patch doesn't fix any actual issue since nthreads = min_t(unsigned int, num_present_cpus(), MVPP2_MAX_THREADS). On all current Armada platforms, the number of CPU's is less than MVPP2_MAX_THREADS.
