💅 dfl_fpga_fea..._devs_remove(9) 💅

okay so first things first, this is a page straight out of the Kernel API Manual — yes, that Kernel API Manual — and it's about one very specific little function. it's short, it's sweet, and it's literally the cleanup era of the FPGA world 🌸

---

✨ NAME ✨

dfl_fpga_feature_devs_remove — remove all feature devices 🧹

---

🦋 SYNOPSIS 🦋

void dfl_fpga_feature_devs_remove (struct dfl_fpga_cdev *cdev );

like, that's it. that's the whole signature. no return value, bestie — it's a void function, it just does the thing and dips 💅

---

🎀 ARGUMENTS 🎀

• cdev — the fpga container device. that's your main character right there 👑 this is the container device you're handing over so it can get removed.

---

🔥 DESCRIPTION 🔥

okay so here's the vibe: this function removes the container device and all the feature devices under the given container device. all of them. the whole little family. no cap 🫶

so you pass in the cdev (the container device) and it's like "aight, everybody out" — container device gone, every feature device nested under it gone too. it's giving group eviction notice ngl 💀
