ata_sff_prereset — prepare SFF link for reset

okay so this is the “get ready before the reset” moment, bestie. It’s from the Kernel API Manual, and it’s literally here to prepare an SFF link for reset. It’s giving pre-reset prep energy, and honestly? slay. 💅🎀

📜 SYNOPSIS 📜

int ata_sff_prereset (struct ata_link *link , unsigned long deadline );

🫶 ARGUMENTS 🫶

• link — SFF link to be reset. yes, that’s the main character. 🦋
• deadline — deadline jiffies for the operation. ⏳

🌸 DESCRIPTION 🌸

The SFF link link is about to be reset — so initialize it first, no cap. It first calls ata_std_prereset and waits for !BSY if the port is being softreset. 💖

LOCKING: Kernel thread context (may sleep). so like, it’s allowed to snooze, bestie. 😴

🎁 RETURN 🎁

Always 0. that’s the whole answer, periodt. ✨
