💅 ax_prepare_t...fer_hardware(9) 💅

okay bestie, so this is a page straight outta the Kernel API Manual and it's lowkey one of the shortest ones you'll ever read, which honestly? slay. it's giving "small but mighty" energy fr fr. let's get into it 🫶

✨ NAME ✨

ax_prepare_transfer_hardware — literally just preps the hardware for a transfer. that's it. that's the whole vibe check. 🎀 no cap.

---

🌸 SYNOPSIS 🌸

int ax_prepare_transfer_hardware (struct spi_controller *ctlr );

so you hand it a ctlr and it hands you back an int. simple as that, babes. 💖

---

🦋 ARGUMENTS 🦋

• ctlr — pointer to the spi_controller structure, which is the lil struct that's carrying all the info about the controller. think of it as the controller's whole personality card. 👑

---

⭐ DESCRIPTION ⭐

so what does this thing actually do? it enables the SPI host controller. periodt. 💅 that's the entire description, bestie — she's short, she's sweet, she ate and left zero crumbs. no extra lore, no hidden side quests. 🔥

🌈 RETURN 🌈

0 — always. every single time. iconic consistency honestly, we stan a function that doesn't keep you guessing. 👑 no error codes, no plot twists, just 0 forever. ⭐
