usb_role_swi...nd_by_fwnode(9)

✨ NAME ✨

usb_role_switch_find_by_fwnode — bestie, this is the one that finds you a USB role switch using its fwnode 💅 (and yes, this is from the Kernel API Manual, so we're being ✨ official ✨ today)

🌸 SYNOPSIS 🌸

struct usb_role_switch * usb_role_switch_find_by_fwnode (const struct
fwnode_handle *fwnode );

ok so like, it hands you back a struct usb_role_switch * — noted 👑

🎀 ARGUMENTS 🎀

• fwnode — the fwnode of the USB Role Switch 💖 like, the lil identity tag of the switch you're looking for, no cap

🦋 DESCRIPTION 🦋

So here's the tea, bestie: this function finds the role switch that goes with fwnode and returns it. Simple. Iconic. Main character energy fr fr 🌈

But the part you cannot skip: the reference count for the found switch is incremented. The way that matters — the switch you get back is holding a reference, so it's on you to deal with that properly later. Don't just ghost it 😭
