, struct device *supplier );

that's it, that's the whole vibe check 🔥

🎀 ARGUMENTS 🎀

• th — a reference to the transport handle you wanna use. no drama, just vibes ✨
• supplier — a reference to the device supplier you're managing. and listen, this one is strict: it cannot be NULL or ERR_PTR. like, it literally cannot 💀 don't try it.

🦋 DESCRIPTION 🦋

okay so here's the tea 🍓: putting a supplier does different things depending on the current state of scmi_transport_supplier.available, and honestly? it's giving state machine realness 👑

• NOT_READY/BUSY — the supplier gets set as the new available device. yes queen, this is your moment: you can use this to make available a supplier OR to stop using one. dual purpose icon 🌈
• AVAILABLE — if the supplier you're disposing of matches the one currently available, we roll back to the NOT_READY state. and any other attempt to override an available supplier with a new one? rejected 🙈 which effectively enforces one single supplier. one supplier only, no cap, periodt 💅
