stm32_firewa...r_unregister(9)

💅 stm32_firewall_controller_unregister — the un-registering era

okay so bestie, welcome to the Kernel API Manual ✨ (yes that's the manual name, we're fancy now). Today's main character is stm32_firewall_controller_unregister(9) — and yeah the header truncates it to stm32_firewa...r_unregister(9) because even manpages need a little drama and an ellipsis moment 🎀

---

✨ NAME ✨

stm32_firewall_controller_unregister — literally the function that unregisters a firewall controller from the STM32 firewall framework. that's it, that's the vibe 🦋

---

✨ SYNOPSIS ✨

void stm32_firewall_controller_unregister (struct
stm32_firewall_controller *firewall_controller );

it returns void, so like… no return value, no exit status, nothing to check afterwards. it just does the thing and dips 💅

---

✨ ARGUMENTS ✨

• firewall_controller — the firewall controller you want to unregister. that's the whole argument. hand it over and it's out of the framework, no cap 🫶 the type is struct stm32_firewall_controller *, so it's a pointer, bestie, don't @ me.

---

✨ SEE ALSO ✨

• Kernel file ./include/linux/bus/stm32_firewall.h — go read the header, it's giving source of truth 📖
• STM32_PERIPHERAL_FIREWALL(9)
• struct stm32_firewall_controller(9)
• stm32_firewall_controller_register(9) — the reverse icon, the register to this unregister 🔥
• stm32_firewall_populate_bus(9)

like the whole friend group is here, iykyk 🌸

ngl if you got here it's probably because something is being torn down and you need to know exactly which call does it — and it's this one, periodt 🧚

kisses, this page lived in ./include/linux/bus and it's dated October 2026 — see you in the next release, mwah 💖🌈
