📦 version 7.3.1, in nixpkgs unstable

✨ ishtp_fw_cl_by_uuid ✨

okay so bestie, welcome to the kernel API manual for ishtp_fw_cl_by_uuid(9) 💅 — yes the (9) means it's a kernel function, we're in the big leagues now, and honestly? it's giving "small function, huge responsibility." Let's get into it 🫶

🌸 SYNOPSIS 🌸

int ishtp_fw_cl_by_uuid (struct ishtp_device *dev , const guid_t *uuid
);

like, that's literally the whole signature. two arguments, one int coming back at you. no cap. ✨

🎀 ARGUMENTS 🎀

  • dev — the ishtp device, aka the main character of this whole operation 👑
  • uuid — the uuid of the client you're hunting for 🔍 like, this is the thing you're searching by, bestie

🦋 DESCRIPTION 🦋

So what does it do? It searches for a firmware client using its UUID. That's it. That's the vibe. You hand it a device and a UUID, it goes looking through the firmware clients, and it comes back with the index. Simple, clean, iconic. ⭐

🔥 RETURN 🔥

You get back the fw client index 🌈 — or -ENOENT if it's not found 😭 which, yeah, that's the "bestie she's not here" error code. fr fr.

Heads up: -ENOENT means not found, so if you get that back, don't go looking for a bug in your code first — the client legit just isn't there 💀

like, that's the whole group chat, iykyk 🧚

kisses and good luck out there, bestie — this one's from the ./drivers/hid/intel-ish-hid/ishtp era, stamped October 2026, and it's the ishtp_fw_cl_by_uuid(9) page. go find those clients 💖✨🎀
