The following commit has been merged in the master branch:
commit 56989f6d8568c21257dcec0f5e644d5570ba3281
Author: Johannes Berg <johannes.berg at intel.com>
Date:   Mon Oct 24 14:40:05 2016 +0200

    genetlink: mark families as __ro_after_init
    
    Now genl_register_family() is the only thing (other than the
    users themselves, perhaps, but I didn't find any doing that)
    writing to the family struct.
    
    In all families that I found, genl_register_family() is only
    called from __init functions (some indirectly, in which case
    I've add __init annotations to clarifly things), so all can
    actually be marked __ro_after_init.
    
    This protects the data structure from accidental corruption.
