ok so bestie, welcome to aer_remove from the Kernel API Manual — this is the little cleanup queen of the PCI Express world, and honestly she ate 💅

like, literally just tidy up and go home, no cap.

---

🌸 SYNOPSIS 🌸

void aer_remove (struct pcie_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — pointer to the pcie_dev data structure 🦋 (yes bestie, that's the whole vibe of this argument, she's just a pointer and she knows it)

---

💖 DESCRIPTION 💖

so here's the tea ☕ — aer_remove gets invoked when the PCI Express bus unloads, or when the AER probe fails 😭. that's it, that's the whole job. she shows up, cleans up resources, and dips ✨ periodt.

highkey important: this is the cleanup function. she's not out here doing main character work, she's the responsible bestie who makes sure nothing's left lying around when the bus leaves the group chat 🧚
