  • offset — the register offset you're performing the action on, very demure, very precise ✨
  • value — the value you're writing to the device. the actual content. the moment. 💅
  • timeout — operation timeout, aka how long we're willing to wait before we get impatient 😭

And here's the cute part — since we don't use the buffer argument, we don't have to worry about kmalloc here. No malloc, no stress, no drama. We love a low-maintenance king 👑✨
