devm_framer_create(9)

💖 devm_framer_create(9) — the kernel API manual, but make it make sense 💖

okay bestie, so this is a page straight out of the Kernel API Manual (yes, that one, the devm_framer_create(9) entry), and honestly it's shorter than my attention span, so we're gonna get through it together in like one sip of an iced matcha. 🌸

✨ NAME ✨

devm_framer_create — creating a brand new framer, but the devm way, which is the whole personality of this function

---

✨ SYNOPSIS ✨

struct framer * devm_framer_create (struct device *dev , struct
       device_node *node , const struct framer_ops *ops );

like, look at her. three arguments. returns a struct framer *. iconic. 👑

---

✨ ARGUMENTS ✨

• dev — the device that's doing the creating, i.e. the one making the new framer happen
• node — the device node of the framer (yes, of the framer, not of the device, keep up bestie 🦋)
• ops — the function pointers, aka the little move set for performing framer operations

---

✨ DESCRIPTION ✨

so what does she actually do? she creates a new framer device and adds it to the framer class. that's the main quest. 🎀

but the ✨signature move✨ is that while she's at it, she also associates the device with the framer using devres. and because devres is that girl, it handles the cleanup for you:

On driver detach, the release function is invoked on the devres data, then the devres data is freed.

so: release function runs on the devres data, and then the devres data gets freed. in that order. don't get it twisted. 💅
