✨ issei_fw_cl_find_by_uuid(9) ✨

okay so bestie, welcome to the kernel API manual for issei_fw_cl_find_by_uuid — yes that's the whole name, it's giving "my parents let the compiler name me" 😭 — and honestly? This one's a little cutie. It's from the Kernel API Manual and it does exactly one thing: it finds a firmware client by uuid. Periodt. 💅

🌸 NAME 🌸

issei_fw_cl_find_by_uuid — find firmware client by uuid

🦋 SYNOPSIS 🦋

struct issei_fw_client * issei_fw_cl_find_by_uuid (struct issei_device
*idev , const uuid_t *uuid );

lowkey just look at it. two args in, one pointer out. main character function energy fr fr 🎀

🎀 ARGUMENTS 🎀

  • idev — the issei device object. like, the whole vibe you're searching inside, y'know?
  • uuid — the uuid to search by it. that's the thing you're hunting for 👑

👑 DESCRIPTION 👑

So here's the tea 🍓 — this should be called under idev->client_lock. Not "it'd be nice if", not "if you feel like it". Should be called under idev->client_lock. Lock it up first, bestie, no cap. 🔒

🌈 RETURN 🌈

  • pointer to firmware client object if found 💖
  • NULL on failure 😭

that's it, that's the whole return contract. simple, iconic, ate.
