Subject: [PATCH net-next 08/11] mlxsw: spectrum: acl: Remove
 mlxsw_afk_encode() block range args and key/mask check

From: Jiri Pirko <jiri@...lanox.com>

Since two remaining users of mlxsw_afk_encode() do not specify
block ranges to work on, remove the args. Also, key/mask is always
non-NULL now, so skip the checks.
