pxa_ep_queue(9)

🌸 NAME 🌸

okay so welcome to the Kernel API Manual, bestie — this is pxa_ep_queue(9), and she's here to Queue a request into an IN endpoint. That's the whole name, no cap. 💅

✨ SYNOPSIS ✨

int pxa_ep_queue (struct usb_ep *_ep , struct usb_request *_req , gfp_t
gfp_flags );

🎀 ARGUMENTS 🎀

• _ep — the usb endpoint. that's the vibe.
• _req — the usb request. iconic.
• gfp_flags — flags. yes, just flags, she's mysterious.

🦋 CONTEXT 🦋

This one runs in thread context, or from the interrupt handler in the special case of ep0 setup: (irq->handle_ep0_ctrl_req->gadget_setup->pxa_ep_queue). Lowkey important, highkey cute. 🫶

💖 DESCRIPTION 💖

Returns 0 if succedeed, error otherwise. That's it. That's the description. (Yes, "succedeed" is exactly how it's written — I don't make the rules. 😭)
