💅 usb_role_switch_get_role(9)

okay bestie, welcome to the Kernel API Manual, and buckle up because we're talking about usb_role_switch_get_role — literally the "hey, what role is this thing playing rn?" function. 🎀

---

✨ NAME ✨

usb_role_switch_get_role — bestie, it gets the USB role for a switch. that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

enum usb_role usb_role_switch_get_role (struct usb_role_switch *sw );

---

🦋 ARGUMENTS 🦋

• sw — the USB role switch in question. the main character of this whole operation. 👑

---

💅 DESCRIPTION 💅

so here's the tea, and it lowkey depends on the role-switch-driver. this function is giving you one of two things:

• a cached value of the last role that was set 🫶
• or it actually reads back the actual value from the hardware 🔥

which one you get? that's the driver's call, not ours. no cap. ✨
