mpi3mr_add_expander_phy(9)

✨ NAME ✨

okay bestie, meet mpi3mr_add_expander_phy(9) — it's from the Kernel API Manual, and its whole vibe is literally report expander phy to transport. no cap, that's the name-and-description combo, and yes the spelling is exactly phy, lowercase, we respect it. 🦋

---

🌸 SYNOPSIS 🌸

here's the signature, copied exactly because bestie we do not mess with C types:

int mpi3mr_add_expander_phy (struct mpi3mr_ioc *mrioc , struct
       mpi3mr_sas_phy *mr_sas_phy , struct mpi3_sas_expander_page1 expander_pg1
       , struct device *parent_dev );

the return type is int, and the function name and all the argument types are exactly as above. iconic. ✨

---

💅 ARGUMENTS 💅

bestie, there are four arguments, and they are all right here:

• mrioc — Adapter instance reference. the adapter's whole reference vibe. 🫶
• mr_sas_phy — Internal Phy object. yes, capital P in Phy, we keep it exactly. 💖
• expander_pg1 — SAS Expander page 1. that's the SAS Expander page 1 data, periodt.
• parent_dev — Parent device class object. the parent-device class object, right there in the signature. 🌈

---

🔥 RETURN 🔥

• 0 for success.
• non-zero for failure.

that's literally the whole return vibe: 0 for success, non-zero for failure. 😭
