  --- BEGIN ISSUE ---
  The DependencyMixin is being deprecated.
  ### Summary
  
  When I use the module to blacklist a kernel module, a warning appears.
  
  ### Issue Type
  
  Bug Report
  
  ### Component Name
  
  kernel_blacklist
  
  ### Ansible Version
  
  ```console (paste below)
  $ansible --version
  ansible [core 2.15.0]
    config file = None
    configured module search path = ['/home/bandura/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
    ansible python module location = /home/bandura/.local/lib/python3.9/site-packages/ansible
    ansible collection location = /home/bandura/.ansible/collections:/usr/share/ansible/collections
    executable location = /home/bandura/.local/bin/ansible
    python version = 3.9.2 (default, Feb 28 2021, 17:03:44) [GCC 10.2.1 20210110] (/usr/bin/python3)
    jinja version = 3.1.2
    libyaml = True
  ```
  
  
  ### Community.general Version
  
  ```console (paste below)
  $ansible-galaxy collection list community.general
  
  # /home/bandura/.local/lib/python3.9/site-packages/ansible_collections
  Collection        Version
  ----------------- -------
  community.general 7.0.1
  ```
  
  
  ### Configuration
  
  ```console (paste below)
  $ansible-config dump --only-changed
  CONFIG_FILE() = None
  ```
  
  
  ### OS / Environment
  
  Debian 11-based
  
  ### Steps to Reproduce
  
  <!--- Paste example playbooks or commands between quotes below -->
  ```yaml (paste below)
  - name: Blacklist old kernel module
    become: true
    community.general.kernel_blacklist:
      name: x_tables
  ```
  
  
  ### Expected Results
  
  No warning
  
  ### Actual Results
  
  Works, but with warning.
  ```console (paste below)
  TASK [install-nftables : Blacklist old IPv4 kernel module] *********************
  [DEPRECATION WARNING]: The DependencyMixin is being deprecated. Modules should 
  use community.general.plugins.module_utils.deps instead. This feature will be 
  removed from community.general in version 9.0.0. Deprecation warnings can be 
  disabled by setting deprecation_warnings=False in ansible.cfg.
  ```
