mpi3mr_cleanup_resources(9)

💖 NAME 💖

mpi3mr_cleanup_resources — bestie, this is the "free PCI resources" girlie ✨ and yes she's in the Kernel API Manual, we love a technical queen 👑

---

🌸 SYNOPSIS 🌸

void mpi3mr_cleanup_resources (struct mpi3mr_ioc *mrioc );

okay so she returns void, she takes exactly one arg, that's the whole vibe check 🫶

---

🎀 ARGUMENTS 🎀

• mrioc — the adapter instance reference 💅 like, the actual controller you're working with, hand her over

---

🦋 DESCRIPTION 🦋

So what does she do, you ask? Two things, no cap:

• Unmaps PCI device memory 🧚
• Disables the PCI device 💀

That's it. That's the whole gig. She's lowkey the cleanup crew — the opposite of mpi3mr_setup_resources(9) if you catch my drift, iykyk. Unmap the memory, turn the device off, mic drop 🎤✨

---

⭐ RETURN ⭐

Okay so the page literally says: 0 on success and non-zero on failure. The signature up top says void. Not me noticing that 🙈 but I'm just the messenger, fr fr. The docs said it, so it's staying. 💖

✨ and that's the whole page, bestie — mwah 💋

Sign-off time 🎀 this little beauty lives in ./drivers/scsi/mpi3mr, dated October 2026, filed under the Kernel API Manual — slay, she's documented, periodt 💅👑
