_aggregate_profiles(9)

💅 _aggregate_profiles — aggregate the profiles for the legacy sysfs interface

okay bestie, welcome to the kernel API manual for _aggregate_profiles(9). she's a little helper living in the ACPI platform profile corner of the kernel, and her whole job is literally right there in the name: aggregating the profiles for the legacy sysfs interface. no cap. ✨

---

🌸 SYNOPSIS 🌸

int _aggregate_profiles (struct device *dev , void *data );

that's the whole vibe check — she takes two things and hands you back an int. simple, iconic, done. 🎀

---

🦋 ARGUMENTS 🦋

• dev — the device. yes, the device. she needs to know which one we're talking about, bestie. 💖
• data — the profile to return. this is the payload you're passing through, and it's a void *, so it's giving mystery-box main character energy. 🎁

---

⭐ RETURN ⭐

• 0 on success — slay, everything worked. 🥳
• -errno on failure — not slay, something went wrong, and the negative errno tells you what. 😭
