Subject: [PATCH -next] coresight: core: Make symbol 'csdev_sink' static
Date:   Fri, 9 Apr 2021 01:32:15 +0000

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")
