💅 of_dp_aux_ep_destroy(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a lil function named of_dp_aux_ep_destroy, and honestly? it's giving cleanup crew energy. let's get into it 🧹✨

✨ NAME ✨

of_dp_aux_ep_destroy — Destroy an DP AUX endpoint device 🎀

🦋 SYNOPSIS 🦋

int of_dp_aux_ep_destroy (struct device *dev , void *data );

🌸 ARGUMENTS 🌸

  • dev — The device to destroy. that's the main character right there, we're sending it off 💅
  • data — Not used. literally just vibing in the parameter list, doing absolutely nothing, respect 🫶

⭐ DESCRIPTION ⭐

okay so here's the tea: this function is just used as a callback by of_dp_aux_depopulate_bus, and it gets called for _all_ of the child devices of the device that's providing the AUX bus. all of them. every single one. no cap 😭

but we're picky (in a slay way) — we'll only act on those that are of type "dp_aux_bus_type". everyone else? not our problem, we don't see it 💀

this function is effectively an inverse of what's in of_dp_aux_populate_bus. like, populate's mirror image, its opposite twin, its "you go girl" counterpart 🔥

NOTE: since we only populate one child then it's expected that only one device will match all the "if" tests in this function and get to the device_unregister. so like… one winner, one ticket to the unregister party 🎟️👑

💖 RETURN 💖

0 if no error or negative error code. simple! clean! iconic! ✨
