Subject: [PATCH 4.19 004/131] crypto: mxs-dcp - make symbols sha1_null_hash and sha256_null_hash static

From: Wei Yongjun <weiyongjun1@...wei.com>

commit ce4e45842de3eb54b8dd6e081765d741f5b92b56 upstream.

Fixes the following sparse warnings:

drivers/crypto/mxs-dcp.c:39:15: warning:
 symbol 'sha1_null_hash' was not declared. Should it be static?
drivers/crypto/mxs-dcp.c:43:15: warning:
 symbol 'sha256_null_hash' was not declared. Should it be static?

Fixes: c709eebaf5c5 ("crypto: mxs-dcp - Fix SHA null hashes and output length")
