💅 sl82c105_bridge_revision(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual page for sl82c105_bridge_revision. literally the whole vibe is "find bridge version" and honestly? she's giving tiny-but-important 💅

🌸 NAME 🌸

sl82c105_bridge_revision — find bridge version 🎀

---

✨ SYNOPSIS ✨

int sl82c105_bridge_revision (struct pci_dev *pdev );

---

🫶 ARGUMENTS 🫶

• pdev — the PCI device for the ATA function 💖 that's the one you're handing in, no cap

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function goes and locates the PCI bridge that's associated with the ATA function. and providing it's a Winbond 553, she reports the revision. iconic behavior, honestly 👑

but listen — if it cannot find a revision, or it can't find the right device? it returns -1 😭 that's the whole mood. no revision, no device, no vibes, just -1.

fr fr, -1 is the "couldn't make it happen" answer here — revision found or device found is the slay path, everything else is -1 🫠
