[PATCH v2 01/68] drm/mipi-dsi: Detach devices when removing the host

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Whenever the MIPI-DSI host is unregistered, the code of
mipi_dsi_host_unregister() loops over every device currently found on that
bus and will unregister it.

However, it doesn't detach it from the bus first, which leads to all kind
of resource leaks if the host wants to perform some clean up whenever a
device is detached.

Fixes: 068a00233969 ("drm: Add MIPI DSI bus support")
