💖 i2c_free_slave_host_notify_device 💖

okay so bestie, we're in the Kernel API Manual today and this one is a lil cutie — a single function, no drama, no flags, just vibes and a pointer. let's get into it 🫶

✨ NAME ✨

i2c_free_slave_host_notify_device — the one that frees the client for SMBus host-notify support 🌸

---

✨ SYNOPSIS ✨

void i2c_free_slave_host_notify_device (struct i2c_client *client );

that's it. that's the whole thing. void in, void out, no return value to stress about 💅

---

✨ ARGUMENTS ✨

• client — the client to free 🎀 literally just hand it the client and it's done.

---

✨ CONTEXT ✨

can sleep 😴

fr fr, this one is allowed to sleep — so don't be calling it from somewhere that can't, okay? no cap, that's the whole context note.

---

✨ DESCRIPTION ✨

so what does it do? it frees the i2c_client that was allocated via i2c_new_slave_host_notify_device 🦋

that's the whole plot. you got a client from the "new" function, and this is the matching "free" function — the cleanup bestie to its creation bestie. iconic symmetry, honestly 👑
