[PATCH -next] coresight: core: Make symbol 'csdev_sink' static

From: Wei Yongjun
Date: Thu Apr 08 2021 - 21:22:26 EST


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?

This symbol is not used outside of coresight-core.c, so this
commit marks it static.

Fixes: 2cd87a7b293d ("coresight: core: Add support for dedicated percpu sinks")
