Subject: crypto: chelsio - Make function aead_ccm_validate_input static
Patch-mainline: v4.17-rc1
Git-commit: 1efb892b6c3c716cdcdb4d1e79bebf4c545158d4
References: bsc#1097585 bsc#1097586 bsc#1097587 bsc#1097588 bsc#1097583 bsc#1097584

Function aead_ccm_validate_input is local to the source and does not
need to be in global scope, so make it static.

Cleans up sparse warning:
drivers/crypto/chelsio/chcr_algo.c:2627:5: warning: symbol
'aead_ccm_validate_input' was not declared. Should it be static?
