π media_device_unregister_entity β Kernel API Manual realness
okay bestie, welcome to the media_device_unregister_entity(9) page π this is the one that yeets a media entity out of existence (registration-wise, anyway). buckle up π
β¨ NAME β¨
media_device_unregister_entity β unregisters a media entity. that's it, that's the whole job π
β¨ SYNOPSIS β¨
void media_device_unregister_entity (struct media_entity *entity );
β¨ ARGUMENTS β¨
entityβ pointer to thestruct media_entityyou want unregistered π«Ά yes, the actual struct, hand it over
β¨ DESCRIPTION β¨
so here's the tea β β the moment you call this function, all links associated with the entity and all PADs get automatically unregistered from the media_device. no manual cleanup, no cap, it just handles it for you β¨
and bestie, important vibe check: unregistering an entity will not change the IDs of the other entities π and that previously used ID will never be reused for newly registered entities. like, ever. it's retired. iconic behaviour honestly π
also, when a media device is unregistered, all its entities get unregistered automatically too π so you don't need to do any manual entity unregistration in that case. it's giving "the whole group chat left at once" energy π¦
NOTE ππ The media_entity instance itself must be freed explicitly by the driver if required. the unregister does not free it for you β that's on you, main character. don't leave it hanging π
