fbtft_probe_common(9)

💅 NAME 💅

fbtft_probe_common — the generic probe() helper function, aka the little guy who sets everything up for you ✨ (this is from the Kernel API Manual, bestie, we're in kernel-land now 🧚)

---

🎀 SYNOPSIS 🎀

int fbtft_probe_common (struct fbtft_display *display , struct
spi_device *sdev , struct platform_device *pdev );

three args, one mission, that's the whole vibe 💫

---

🌸 ARGUMENTS 🌸

• display — the display properties 🖼️ literally the whole personality of your screen lives here
• sdev — the SPI device 🔌
• pdev — the platform device 🧱

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕: this function allocates, initializes and registers a framebuffer. all three. in one go. it's giving main character energy fr fr 👑

⚠️ one rule bestie: either sdev or pdev should be NULL — like, exactly one of them. don't come in here with both filled in, that's not the move 🙈

---

⭐ RETURN ⭐

• 0 if successful — slay 💖
• negative if error — not slay 😭 but at least it tells you
