regmap_field_alloc(9)

💖 regmap_field_alloc(9) — like, the whole vibe 💖

okay so bestie, welcome to the Kernel API Manual 🎀 — yes that's the manual name, and yes it's giving "I read documentation for fun" energy, which is iconic of you tbh. today we're talking about regmap_field_alloc, and ngl it's one of the girlies who does exactly what her name says. no plot twist. slay.

---

✨ SYNOPSIS ✨

struct regmap_field * regmap_field_alloc (struct regmap *regmap , struct reg_field reg_field );

that's literally it. two arguments in, one pointer out. main character energy fr fr 🔥

---

🌸 ARGUMENTS 🌸

• regmap — the regmap bank where this register field is living. think of it as the address of the group chat this register field is in 💅
• reg_field — the register field itself, chillin' there within the bank. that's the one you're pulling out. 🦋

---

⭐ DESCRIPTION ⭐

so here's the tea ☕: whatever you get back is either an ERR_PTR on error 💀, or a totally valid pointer to a struct regmap_field 💖.

heads up bestie: if you get a real pointer, that thing is yours and you gotta free it once you're done working with it — use regmap_field_free. don't just ghost it, that's a memory leak and we do NOT do that here 🙈
