Hi All, This small patch set add a function for removing all links at a media entity. I found out such a function is needed when media entites that belong to single media device have drivers in different kernel modules. This means virtually all camera drivers, since sensors are separate modules from the host interface drivers. More details can be found in the commits' description. The links removal from a media entity is rather strightforward, but when and where links should be created/removed is not immediately clear to me. I assumed that links should be created/removed only when an entity is registered to its media device, and with the graph mutex held. I'm open to opinions whether it's good or not and possibly suggestions on how those issues could be handled differently.
