mpt3sas_tran...expander_phy(9)

💅 mpt3sas_transport_add_expander_phy — a.k.a. the mpt3sas_tran...expander_phy(9) glow-up ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this one is a function page, and yes the header is literally truncated with ... in the middle which is giving "my mom named the file". we move.

🌸 NAME 🌸

mpt3sas_transport_add_expander_phy — report expander phy to transport 🦋

like, it introduces an expander phy to the transport layer. that's the whole vibe. no cap.

---

✨ SYNOPSIS ✨

int mpt3sas_transport_add_expander_phy (struct MPT3SAS_ADAPTER *ioc ,
struct _sas_phy *mpt3sas_phy , Mpi2ExpanderPage1_t expander_pg1 , struct
device *parent_dev );

it returns an int, it takes four things, and it's literally right there for you to copy 💖

---

🫶 ARGUMENTS 🫶

• ioc — the per adapter object 🌈 like, the whole adapter's main character energy right here.
• mpt3sas_phy — the mpt3sas per phy object 💜 one specific phy, being all individual about it.
• expander_pg1 — expander page 1 📄 yep. that page. page one. iconic.
• parent_dev — the parent device class object 👑 the device that's basically the parent in this whole situation, fr fr.

---

💀 RETURN 💀

0 for success, non-zero for failure. that's it, that's the whole story 🍓

careful bestie — non-zero is failure, so don't go treating any random number like it's a win 😭
