cros_ec_resume(9)

💖 cros_ec_resume 💖

okay so bestie, welcome to the kernel API manual, section 9 — this one's about cros_ec_resume, and honestly it's a little icon of a function. Serving ChromeOS EC device realness, resume-handling energy, the whole vibe. Let's get into it 🫶

---

✨ SYNOPSIS ✨

int cros_ec_resume (struct cros_ec_device *ec_dev );

that's it. that's the whole signature. short, sweet, slays 💅

---

🎀 ARGUMENTS 🎀

• ec_dev — the device you're waking back up. your sleepy little EC. the one you're resuming. that's the whole gig ✨

---

🌸 DESCRIPTION 🌸

so here's the tea: drivers can call this when they need to handle a resume event. that's genuinely it — it's the resume handler, it does the resume thing, and it's there for drivers to use.

no cap, it's not out here doing extra. it's not the main character of the resume saga, it's just... one of the cast 🌈

lowkey iconic that a function this chill exists in the kernel. not every resume hook needs to be dramatic.

---

⭐ RETURN ⭐

• 0 — always. like, always always. fr fr. it returns zero, every single time, no matter what. no error codes, no surprises, no plot twists 💀✨
