dev_pm_opp_set_opp(9)

💅 dev_pm_opp_set_opp — kernel API manual, bestie edition ✨

okay so real talk, this one is from the Kernel API Manual, section 9, and it's lowkey a little icon. let's get into it 🫶

---

🌸 NAME

dev_pm_opp_set_opp — configure the device for an OPP. that's it. that's the whole vibe check. 💖

---

✨ SYNOPSIS

int dev_pm_opp_set_opp (struct device *dev , struct dev_pm_opp *opp );

literally two args, no drama. we love a signature that minds its own business. 🎀

---

🦋 ARGUMENTS

• dev — the device we're doing this whole operation for. she's the main character here 👑
• opp — the OPP we're setting to. the destination, the moment, the ~look~ 💅

---

💜 DESCRIPTION

so basically this routine configures the device based on the properties of the OPP you hand it. that's the entire plot. no subplots, no twist endings — you pass an OPP, the device gets configured off its properties. slay. 🔥

---

🌈 RETURN

0 on success, and a negative error number otherwise. so if you get anything below zero, that's not a win, bestie — go read the error code, ngl 😭
