rproc_remove_subdev(9)

💅 rproc_remove_subdev — a Kernel API Manual moment 🌸

okay so bestie, you know how rproc_add_subdev is the glow-up era where you register a subdevice? yeah. this page is the other side of that story — it's the un-register. welcome to the Kernel API Manual for rproc_remove_subdev, section 9, and honestly it's giving "cleanup era" and we love that for us.

✨ NAME ✨

rproc_remove_subdev — remove a subdevice from a remoteproc 🎀

like, take it off the list. gently. it's done its job.

---

✨ SYNOPSIS ✨

void rproc_remove_subdev (struct rproc *rproc , struct rproc_subdev
*subdev );

no cap, it returns nothing — void is the whole personality. it just does the thing and exits. iconic 💅

---

✨ ARGUMENTS ✨

• rproc — the rproc handle you're removing the subdevice from. this is the main character of the operation, the one who has to let go 😭
• subdev — the subdev handle, previously registered with rproc_add_subdev. yes this is the same handle from that function. it's a callback to an earlier episode. iykyk 🦋

fr fr, these two need to match up — subdev is the one that was registered with rproc_add_subdev beforehand. that's the whole vibe check.
