✨ SYNOPSIS ✨

void release_firmware (const struct firmware *fw );

no cap, that's the whole signature. void in, void out, very demure, very mindful 🎀

---

🦋 ARGUMENTS 🦋

• fw — the firmware resource you're releasing. that's the one. the main character of this function. hand it over and let it go 🌈
