ksz_irq_phy_free(9)

💖 ksz_irq_phy_free — the kernel API manual, but make it make sense 💖

okay so bestie, welcome to ksz_irq_phy_free(9), straight out of the Linux kernel API manual ✨ this little icon is all about the KSZ device, and honestly? she's lowkey the cleanup crew of the driver world. let's get into it 🫶

---

✨ NAME ✨

ksz_irq_phy_free — release those IRQ mappings for the PHYs in the KSZ device, no cap 💅

---

🌸 SYNOPSIS 🌸

void ksz_irq_phy_free (struct ksz_device *dev );

that's it. that's the whole signature. she takes one pointer and returns literally nothing (void), because she's a giver 💜

---

🎀 ARGUMENTS 🎀

• dev — a pointer to the struct ksz_device structure. that's the KSZ device bestie, she needs to know which device we're freeing stuff on 🦋

---

🌈 DESCRIPTION 🌈

so what she actually does: she releases any IRQ mappings that were previously assigned to the active PHYs in the KSZ switch 👑 how? by disposing of each mapped IRQ inside the user_mii_bus structure. that's the whole assignment. tidy, iconic, done ✨

think of her as the friend who helps you pack up after the party — every mapped IRQ gets put away properly so nothing's left lingering 😭💖

ok real talk: ksz_irq_phy_setup(9) is literally her counterpart — she sets the IRQ mappings up, ksz_irq_phy_free takes them back down. balance. harmony. main character duo energy 🔥
