💅 devm_pwrseq_get(9)

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is devm_pwrseq_get — the managed girlie of the power-sequencing world. she's iconic, she's got your back, and she handles cleanup so you don't have to. periodt. ✨

---

🌸 NAME 🌸

devm_pwrseq_get — literally the managed variant of pwrseq_get(). that's it, that's the tweet. 💖

---

🎀 SYNOPSIS 🎀

struct pwrseq_desc * devm_pwrseq_get (struct device *dev , const char *target );

look at her. so clean. so demure. 🦋

---

👑 ARGUMENTS 👑

• dev — the device that's asking for the sequencer, and (this is the important part, no cap) the device that also manages its lifetime. so like, she's your device and your built-in cleanup crew. 🫶
• target — the name of the target that the sequencer exposes, i.e. the specific thing this device wants to reach. you gotta know where you're going, bestie. 🎯

---

⭐ RETURN ⭐

you get back a shiny new power sequencer descriptor for your consumer driver to use — or ERR_PTR on failure. 😭 so yeah, always check your pointers, iykyk. 💀
