💅 devm_lwmi_tm_register_notifier — the Linux Kernel API Manual, but make it cute

okay so bestie, this page lives in the Kernel API Manual (that's man 9 territory, aka the big-kid section — very main character energy), and it's all about one lil helper that registers a notifier and cleans up after itself. no cap, it's giving "responsible adult" 🎀

✨ NAME ✨

devm_lwmi_tm_register_notifier — adds a notifier to the blocking notifier chain. that's it, that's the whole vibe 🦋

✨ SYNOPSIS ✨

int devm_lwmi_tm_register_notifier (struct device *dev , struct
       notifier_block *nb );

🌸 ARGUMENTS 🌸

  • dev — the parent device of the notifier_block struct. basically the grown-up in charge of this whole situation 🫶
  • nb — the notifier_block struct you're registering. the actual notifier, the star of the show ⭐

💖 DESCRIPTION 💖

so here's the tea, bestie 👑

First, it calls lwmi_tm_register_notifier to register your notifier block onto the thermal mode notifier chain. literally just handing it over to the chain, no drama ✨

Then — and this is the iconic part — it adds devm_lwmi_tm_unregister_notifier as a device managed action, so the notifier block automatically unregisters itself when the parent device gets removed. you don't have to lift a finger. it's giving set-it-and-forget-it. it's giving the devm machinery doing your chores for you 💅🫶

🔥 RETURN 🔥

0 on success, or an error code. that's the whole range, no in-between, periodt 💀

ngl bestie, if you're reading this at 3am debugging a Lenovo WMI driver, drink some water and remember: the notifier unregisters itself. you don't have to. 🌈

okay that's the page!! 🌸 and for the sign-off: this lil beauty comes from ./drivers/platform/x86/lenovo, stamped October 2026, and yeah it's filed under devm_lwmi_tm...ter_notifier(9) which is lowkey an unserious filename but we love her anyway 💜🎀 slay, bye!! 💅✨
