The sparse tool complains as follows: drivers/hwtracing/coresight/coresight-core.c:26:1: warning: symbol '__pcpu_scope_csdev_sink' was not declared. Should it be static? As csdev_sink is not used outside of coresight-core.c after the introduction of coresight_[set|get]_percpu_sink() helpers, this change marks it static.
