devm_nvmem_device_put(9)

💅 devm_nvmem_device_put — kernel API manual, but make it make sense

okay so bestie, this is devm_nvmem_device_put(9) from the Kernel API Manual, and it's honestly such a short little icon. its whole job? putting back an nvmem device you already got. that's it. that's the function. 🎀

✨ NAME ✨

devm_nvmem_device_put — put already got nvmem device

like, you grabbed it, and now you're putting it back. balanced. symmetrical. we love a full circle moment. 🦋

---

🌸 SYNOPSIS 🌸

void devm_nvmem_device_put (struct device *dev , struct nvmem_device
*nvmem );

no return value, no drama — it's void, she simply does the thing and leaves. 👑

---

💖 ARGUMENTS 💖

• dev — the Device that uses the nvmem device. the main character of the hardware world, fr fr. 🌟
• nvmem — pointer to nvmem device allocated by devm_nvmem_cell_get, that needs to be released. so like, if you got it from devm_nvmem_cell_get, this is the one you hand back. don't be out here releasing random pointers, bestie. 🙈

lowkey important: that nvmem pointer has to come from devm_nvmem_cell_get — that's the origin story the docs specify. iykyk. 💅
