ishtp_set_drvdata(9)

✨ ishtp_set_drvdata — set client driver data ✨

okay so this is a page out of the Kernel API Manual, bestie, and it's about ishtp_set_drvdata(9) 💅 it's a tiny little function with main character energy — it does literally one thing and it does it slayfully.

---

🌸 SYNOPSIS 🌸

void ishtp_set_drvdata (struct ishtp_cl_device *cl_device , void *data
);

yeah that's the whole thing. void return, two args, she's lowkey minimal and we respect it 🫶

---

🎀 ARGUMENTS 🎀

• cl_device — the client device instance 💖 like, the actual device object you're attaching stuff to
• data — the driver data that needs to be set ✨ whatever blob of a pointer you're carrying around, this is where it goes

---

🦋 DESCRIPTION 🦋

so the whole vibe is: it sets the client driver data onto cl_device->driver_data. that's it. that's the function. no cap 🧚

think of it as tucking your little pointer into the device's pocket so you can grab it back later — iconic, simple, exactly what it says on the tin 👑

💜 reminder bestie: this one only sets the data. if you're trying to read it back, that's a different function (ishtp_get_drvdata(9), we see you 👀).

and that's the whole page!! ✨ this lives in the ./drivers/hid/intel-ish-hid/ishtp corner of the kernel tree, and this particular cuteness is dated October 2026 🌸 go forth and set that drvdata, you've got this 🎀💖🦋
