💅 pch_udc_pcd_set_wedge(9) — a Kernel API Manual moment

okay so this is a page from the Kernel API Manual, bestie, and it's all about pch_udc_pcd_set_wedge. tiny page, big job: it sets or clears the endpoint halt feature. that's it, that's the whole personality. let's get into it ✨

🎀 NAME

pch_udc_pcd_set_wedge — literally the function that sets or clears the endpoint halt feature.

✨ SYNOPSIS

int pch_udc_pcd_set_wedge (struct usb_ep *usbep );

🫶 ARGUMENTS

• usbep — a reference to the USB endpoint structure. that's the one thing you hand it 💖

🌸 DESCRIPTION

so what happens when you call it? it returns stuff, and here's the whole tea:

• 0 — success 🎉
• a linux error number — failure 😭

that's genuinely the entire description, no cap. short and iconic.

and that's the whole page, bestie!! this little cutie came out of ./drivers/usb/gadget/udc and it's dated October 2026 — a whole main character in the Kernel API Manual lineup. go set (or clear 😌) that halt feature. periodt 💅✨🌸
