💅 pch_udc_svc_control_in(9) — Handle Control IN endpoint interrupts 💅

okay so bestie, welcome to the Kernel API Manual page for pch_udc_svc_control_in(9). This one handles Control IN endpoint interrupts — that's the whole vibe. You hand it dev, and literally nothing comes back (void), so there is no return value to obsess over. Now let's get into the sections, periodt. ✨

🌸 NAME 🌸

pch_udc_svc_control_in - Handle Control IN endpoint interrupts

✨ SYNOPSIS ✨

void pch_udc_svc_control_in (struct pch_udc_dev *dev );

🎀 ARGUMENTS 🎀

• dev — Reference to the device structure. That's the whole argument, bestie — one pointer, main character energy. 🫶
