💅 scmi_transport_supplier_get(9) — aka the "get hold of a supplier" girlie

okay so this is a page from the Kernel API Manual and it's about scmi_transport_supplier_get, which is literally just a little helper bestie whose whole job is getting hold of a supplier. that's it. that's the gig. 🫶

✨ NAME ✨

scmi_transport_supplier_get — a helper to get hold of a supplier 🌸

---

🎀 SYNOPSIS 🎀

struct device * scmi_transport_supplier_get (const struct
scmi_transport_handle *th );

---

🦋 ARGUMENTS 🦋

• th — a reference to the transport handle you wanna use. that's the one. hand it over. 💜

---

👑 DESCRIPTION 👑

ok so real talk, when you try to get a supplier device, there's like a few things it can hand back — and no cap, you gotta be ready for all of them:

• ✨ a ready to use supplier device (which, btw, gets subsequently made unavailable — like, it's yours but also… not forever, iykyk)
• 😭 PTR_ERR(-EPROBE_DEFER) — no supplier is available, like at all
• 💀 PTR_ERR(-BUSY) — the supplier was already taken by a previous get. sorry bestie, someone else called dibs

the way this slaps is that it lets the probe defer and wait when a possible device can be reasonably expected to show up. like, it's not here yet but it's coming, so we wait. main character patience. ⭐

---

🌈 RETURN 🌈

a usable supplier device on Success, or PTR_ERR on Failure. periodt. 🔥
