usb_put_phy(9)

💅 usb_put_phy(9) — from the Kernel API Manual ✨

okay so bestie, welcome to usb_put_phy(9), the little cleanup queen of the USB PHY world. she's short, she's sweet, and honestly she's giving "someone has to do it" energy 🎀

---

🦋 NAME

usb_put_phy — release the USB PHY, no cap 💖

---

✨ SYNOPSIS

void usb_put_phy (struct usb_phy *x );

that's it. that's the whole signature. one argument, returns nothing, zero drama 🙈

---

🍓 ARGUMENTS

• x — the phy returned by usb_get_phy. like, the actual one you got back, not a random one you found lying around, i'm begging you 😭

---

🌸 DESCRIPTION

okay so here's the tea: this function releases a refcount that the caller received from usb_get_phy. that's literally the whole job. you got the phy, you're done with the phy, you put the phy back. balance. harmony. the circle of life 🧚✨

it's for use by USB host and peripheral drivers — so if that's your lane, slay, this is your function. if it's not your lane... why are you here bestie 💀

lowkey important: this is the counterpart to usb_get_phy, so treat them like a matching set. you wouldn't take the phy and never give it back, that's not the vibe 🫶
