drm_dp_tunne...et_new_state(9)

💖 NAME 💖

okay so bestie, this is drm_dp_tunnel_atomic_get_new_state — it grabs the new atomic state for a tunnel. that's it, that's the whole vibe ✨ (and yeah, the header up top got a lil truncated, it's giving drm_dp_tunne...et_new_state(9), but we know her full name 💅)

---

🦋 SYNOPSIS 🦋

struct drm_dp_tunnel_state * drm_dp_tunnel_atomic_get_new_state (struct
       drm_atomic_commit *state , const struct drm_dp_tunnel *tunnel );

like, it hands you back a struct drm_dp_tunnel_state * — no cap 🫶

---

🎀 ARGUMENTS 🎀

• state — the atomic state, bestie. that's the whole context we're working in.
• tunnel — the tunnel you want the state for. the main character of this call, honestly 👑

---

🌸 DESCRIPTION 🌸

Get the new atomic state for tunnel. literally that's the job 😌

it returns the new state, or NULL if the tunnel's atomic state is not in state. so if you get NULL back, don't come for me — that just means it's not there 🙈

so real talk: check for NULL, okay? it's not a "this always works" situation, it's a "this works if the state is in there" situation 💀
