okay so bestie, welcome to the Kernel API Manual entry for gma_power_suspend</p> — yes that's the manual name up there, we're doing this properly ✨

---

🌸 NAME 🌸

gma_power_suspend — the bus callback for suspend. that's it, that's the whole vibe 🫶

---

✨ SYNOPSIS ✨

int gma_power_suspend (struct device *_dev );

literally just one argument, we love a low-maintenance signature 💅

---

🎀 ARGUMENTS 🎀

• _dev — our device 💖 that's our baby, our device, the one we're powering down

---

🦋 DESCRIPTION 🦋

so the PCI layer calls this back during a suspend of the whole system — like, the PCI layer literally rings us up like "hey bestie, we're going down" 😭 and we answer.

what do we do? we perform the necessary shut down steps, and we save enough state that we can undo all of it when resume is called. it's giving "packing a little bag so future-you can find everything again" 🧳✨ no cap, that saved state is the whole point — without it, resume is just standing in a dark room going "…now what" 💀
