devm_regmap_field_free(9)

💅 devm_regmap_field_free — like, the kernel API manual one

okay bestie, welcome to the devm_regmap_field_free(9) page, straight out of the Linux kernel API manual ✨ this is the whole entire page, no skips, no cuts 🎀

---

🌸 NAME 🌸

devm_regmap_field_free — frees a register field that was allocated using devm_regmap_field_alloc. that's it, that's the whole job 💖

---

✨ SYNOPSIS ✨

void devm_regmap_field_free (struct device *dev , struct regmap_field *field );

like, you hand it a device and a field and it takes the field off your hands. icon behaviour, no cap 🫶

---

🦋 ARGUMENTS 🦋

• dev — the device that will be interacted with. this is the dev in question, the main character 💅
• field — the regmap field that should be freed. yes, the one you want gone 🗑️✨

---

💀 DESCRIPTION 💀

so basically, this frees a register field that was allocated using devm_regmap_field_alloc.

and here's the lowkey iconic part: usually drivers don't even need to call this function at all 🫶 because the memory allocated via devm gets freed automatically as per the device-driver life-cycle. the kernel handles it for you. it's giving built-in cleanup, it's giving "not me having to remember to free things" 🙈

but if you do want to free it manually, this is your girl ✨

and that's the whole page bestie, you ate it up 💖✨

sign-off time 🎀 this came from ./drivers/base/regmap, dated October 2026, and it's devm_regmap_field_free(9) — periodt. go free that field (or don't, the kernel's got you) 🦋
