[PATCH -next] crypto: mxs-dcp: make symbols 'sha1_null_hash' and 'sha256_null_hash' static

[Wei Yongjun]

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")

[PATCH] crypto: caam - add SPDX license identifier to all files

[Horia Geantă]

Previously, a tree-wide change added SPDX license identifiers to
files lacking licensing information:
b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files 
with no license")

To be consistent update the rest of the files:
-files with license specified by means of MODULE_LICENSE()
-files with complete license text
-Kconfig
