Subject: [PATCH -next v2] coresight: core: Make symbol 'csdev_sink' static
Date: Fri, 9 Apr 2021 09:49:00 +0000	[thread overview]
Message-ID: <20210409094900.1902783-1-weiyongjun1@huawei.com> (raw)

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.

Reported-by: Hulk Robot <hulkci@huawei.com>

v1 -> v2: remove fixes tag and description.
