Subject: [PATCH -next] integrity: Make function integrity_add_key() static
Date: Wed, 10 Feb 2021 08:01:31 +0000	[thread overview]
Message-ID: <20210210080131.1209889-1-weiyongjun1@huawei.com> (raw)

The sparse tool complains as follows:

security/integrity/digsig.c:146:12: warning:
 symbol 'integrity_add_key' was not declared. Should it be static?

This function is not used outside of digsig.c, so this
commit marks it static.
