The work handlers\nthemselves take dc_lock, producing an ABBA deadlock when a worker is\nin flight at suspend time.\n\n[How]\nSplit the disable path into two phases with opposite locking\ncontracts:\n  1. amdgpu_dm_ism_disable() -- quiesces workers, must NOT hold\n     dc_lock.\n  2. amdgpu_dm_ism_force_full_power() (new) -- drives the ISM FSM\n     back to FULL_POWER_RUNNING, must hold dc_lock.",
