platform_de...ree_irqs_all(9)

💅 NAME 💅

ok so bestie, gather round — this is the manual page for platform_device_msi_free_irqs_all, and it's literally the cleanup queen 👑 of the MSI world. Per the header up top, this lil beauty lives in the Kernel API Manual (section 9, the kernel API section, iykyk), and its whole job is:

platform_device_msi_free_irqs_all — free all the interrupts for @dev 🫶

that's it. that's the gig. she frees all of them. not some. all. no crumbs left behind, periodt 💀✨

---

✨ SYNOPSIS ✨

ok here's the whole dramatic entrance, typed out exactly, don't @ me:

void platform_device_msi_free_irqs_all (struct device *dev );

yep. returns void — she doesn't hand back a status code, she just does the thing and dips 🙈. takes exactly one argument, and no, you cannot skip it, the compiler will absolutely clock you 👀

---

🎀 ARGUMENTS 🎀

one single argument. one. icon behavior honestly:

• dev — the device you wanna free interrupts for 💖 this is your device, the one whose interrupts are getting their goodbye moment. she's the main character of this function call, so pass her in and let the freeing begin 🌸

that's the entire list, bestie — dev and vibes. nothing else. no hidden extras, no surprises 🦋

---

🌈 SEE ALSO 🌈

if you're the type to go down a rabbit hole (respect), here's where to look next:

• the kernel file ./drivers/base/platform-msi.c — that's the actual source, go peek if you're nosy like me 💜
• platform_device_msi_init_and_alloc_irqs(9) — the other half of the story! that one *init`*s and *alloc*ates, this one frees. they're giving setup-and-teardown duo energy, fr fr 🧚✨

---

ngl this page is short and sweet and that's the point — if you're freeing all the interrupts for a device, you already know what you're doing. go off 👑

---

okayyy that's the whole page!! source/version vibe check: this one's filed under ./drivers/base (the Kernel API Manual, section 9 bestie), and it's dated October 2026 📅💖 like... future icon behavior honestly. slay, bye!! 🎀🦋💅
