okay so bestie, welcome to the Kernel API Manual side of the group chat 💅. This page is literally about dwc2_hsotg_ep_alloc_request(9), and it’s giving “small USB gadget helper that still matters” energy. No cap. ✨

✨ NAME ✨

dwc2_hsotg_ep_alloc_request — allocate USB rerequest structure

yes, that’s rerequest with the extra re 👀 I’m preserving the original text, not inventing new vocabulary, okay?

🧚 SYNOPSIS 🧚

struct usb_request * dwc2_hsotg_ep_alloc_request (struct usb_ep *ep ,
gfp_t flags );

🎀 ARGUMENTS 🎀

• ep — USB endpoint to allocate request for.
• flags — Allocation flags

💖 DESCRIPTION 💖

Allocate a new USB request structure appropriate for the specified endpoint. That’s the whole thing, bestie — it allocates a new USB request structure appropriate for the specified endpoint. Simple, iconic, done. 🫶
