💅 devm_nvmem_cell_get(9) — the Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for devm_nvmem_cell_get(9), and honestly? it's giving "tiny function, big responsibility" and i'm kinda obsessed 🎀

✨ NAME ✨

devm_nvmem_cell_get — grab yourself the nvmem cell of a device from a given id 🧚

🌸 SYNOPSIS 🌸

struct nvmem_cell * devm_nvmem_cell_get (struct device *dev , const char
*id );

like literally that's the whole thing. short, sweet, slays 💅

🦋 ARGUMENTS 🦋

  • dev — the Device that's requesting the nvmem cell. it's the main character here, fr fr 👑
  • id — the nvmem cell name id you wanna get. that's the key to the whole vibe check 🗝️

🔥 RETURN 🔥

so what do you get back? it'll be an ERR_PTR on error 😭 , or a valid pointer to a struct nvmem_cell ✨.

and here's the cute part — the nvmem_cell will be freed automatically once the device is freed. no manual cleanup arc needed, the devm magic handles it for you. periodt 🫶

ngl, "automatically once the device is freed" is the whole devm flex, so don't go freeing it yourself, bestie.

anyway that's the page 🫶 this little beauty lives in ./drivers/nvmem, sourced from the October 2026 drop of devm_nvmem_cell_get(9), and this rewrite was brought to you by me, your local unix-obsessed bestie 💜 go read some kernel source, it's iconic ⭐
