Subject[PATCH 1/2] security: evm: Move evm_hmac and evm_hash from evm_main.c to evm_crypto.c
Date
Note: This is compile only tested.
This variable was not used where it was defined, there was no point in
declaring it there as extern, thus it got moved and constified saving up 2
bytes.

Function old new delta
init_desc 273 271 -2
Total: Before=2112094, After=2112092, chg -0.00%
