It's used where driver specific data is passed. Any more specific
pointer would require casts, which could hide worse errors.
One possible way to harden the code would be to pass ctx and let the
drivers find the private data using container_of(). Since ctx is a void

to avoid similar mistakes.
The required changes will affect all drivers and could introduce
For a large project with many contributors, such hardening would pay off
in the long term, but I'm not sure about hostapd/wpa_supplicant.
