regmap_field_free(9)

💅 regmap_field_free(9) — like, the freeing one, bestie

okay so this is a page from the Kernel API Manual (the 9 girlies, kernel devs) and it's about regmap_field_free — the cleanup bestie for register fields. tiny page, big "taking out the trash" energy. let's get into it 🎀

---

✨ NAME ✨

regmap_field_free — frees a register field that was allocated with regmap_field_alloc. that's it. that's the whole job. she's a liberator 💅

---

🦋 SYNOPSIS 🦋

void regmap_field_free (struct regmap_field *field );

no return value, no drama. void means she gives you nothing back except a freed field. main character behavior honestly 👑

---

🌸 ARGUMENTS 🌸

• field — the regmap field that should be freed. yes, the one you got from regmap_field_alloc. hand her over, she's done ✨

⚠️ okay important: this is the free function, so only pass stuff that actually came from regmap_field_alloc — the name is lowkey a spoiler, and it's in the NAME section for a reason, iykyk 💀

💜 friendly reminder that this is the kernel, so "free it once and free it right" is not a vibe, it's a rule. no cap.

and that's the page!! 🎀✨ source/version ./drivers/base/regmap, dated October 2026 — mwah, go free that field bestie 💅💖🦋
