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")
