💖 atmel_lcdfb_alloc_video_memory 💖

okay bestie, welcome to the Kernel API Manual — yes we're in atmel_lcdfb_...video_memory(9) territory and honestly? it's giving niche-but-iconic. grab your strawberry drink 🍓 and let's go.

✨ NAME ✨

atmel_lcdfb_alloc_video_memory — literally just allocates framebuffer memory 🎀 that's it, that's the whole vibe.

---

🌸 SYNOPSIS 🌸

int atmel_lcdfb_alloc_video_memory (struct atmel_lcdfb_info *sinfo );

---

🦋 ARGUMENTS 🦋

• sinfo — the frame buffer you're allocating memory for 💅 like, hand it the framebuffer, it handles the rest, no cap.

---

👑 DESCRIPTION 👑

so here's the tea ☕ — this function is called only from the atmel_lcdfb_probe. only. exclusively. nobody else pulls up. 🙈

and because of that? there's no locking by fb_info->mm_lock around the smem_len setting needed. not because locking isn't cute (it is, in a safety way), but because there's literally only one caller, so the race condition can't even show up to the party. main character energy for the single-caller life ✨
