nvmem_cell_get(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nvmem_cell_get(9)

okay so this is a page from the Kernel API Manual — yes bestie, the kernel, the big scary one, and no it's not that deep, i promise 🫶

✨ NAME ✨

nvmem_cell_get — grab an nvmem cell for your device by name. that's it. that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

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

🦋 ARGUMENTS 🦋

  • dev — the device that's asking for the nvmem cell. like, hi yes it's me, i would like a cell please 👑
  • id — the name of the nvmem cell you want. and listen, this one's a little context-dependent, so pay attention:
    • on DT systems it lines up with the name from the nvmem-cell-names property 🌈
    • on non-DT systems it lines up with the con_id from the lookup entry ⭐

same argument, two different matching rules depending on your setup — iykyk 💫

💀 RETURN 💀

you get one of two things, no in-between:

  • an ERR_PTR if something goes wrong 😭
  • a valid pointer to a struct nvmem_cell if it slays ✨
💖 important bestie note: the nvmem_cell gets freed by the nvmem_cell_put. so like... don't just abandon it, okay? that's not the move.

🔥 SEE ALSO 🔥

all the siblings, cousins, and extended family 👑 the kernel file is ./drivers/nvmem/core.c, and here's literally everyone:

that's 33 entries bestie, i counted, and yes i listed every single one because we don't do half-finished over here 💅

anyway that's the whole page!! this lil beauty lives in ./drivers/nvmem and the version on record is dated October 2026 — mwah, go read your cells, ily, bye 🧚‍♀️💜
