✨ spu2_wordalign_padlen ✨

okay so bestie, welcome to the Kernel API Manual 💖 you're about to read the most unserious-but-serious page in the whole crypto driver, and honestly? it ate. no cap.

---

🌸 NAME 🌸

spu2_wordalign_padlen — literally just here to tell you that SPU2 does not require padding. that's it. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

u32 spu2_wordalign_padlen (u32 data_size );

---

🎀 ARGUMENTS 🎀

• data_size — the length of the data field, in bytes. yes, in bytes. it gets passed in and then... well. read the next section bestie 🙈

---

⭐ RETURN ⭐

it returns the length of the status field padding, in bytes — and on SPU2 that is always 0. always. every single time. zero. nada. not a single byte of padding, she simply doesn't need it 👑 (the data_size argument is honestly just there for the vibes, iykyk 😭)
