[PATCH v7 12/44] [media] media: remove media entity .parent field

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

 



From: Javier Martinez Canillas <javier@xxxxxxxxxxxxxxx>

Now that the struct media_entity .parent field is unused, it can be
safely removed. Since all the previous users were converted to use
the .mdev field from the embedded struct media_gobj instead.
