like… the entire personality of this function is in that one line and honestly? it ate. 💅

🌸 SYNOPSIS 🌸

void ata_tf_from_fis (const u8 *fis , struct ata_taskfile *tf );

that's it. that's the function. void, so it gives you nothing back — the real gift is the taskfile it fills in for you, bestie 🎀

🦋 ARGUMENTS 🦋

• fis — Buffer from which data will be input. this is the source, the origin story, the main character we're reading from 🔥
• tf — Taskfile to output. this is where the magic gets written, the destination, the glow-up container 💖

👑 DESCRIPTION 👑

Converts a serial ATA FIS structure to a standard ATA taskfile. that's it, that's the job — FIS in, taskfile out, no drama, no extra steps, just a clean little glow-up conversion ✨

LOCKING: Inherited from caller.

⚠️ real talk: the locking is inherited from caller. so whatever lock energy you walked in with? that's what you're working with. this function does not sort that out for you — that's a you problem, bestie 😭 plan accordingly, fr fr.
