💖 dwc3_free_one_event_buffer — a Kernel API Manual moment 💖

okay so this is a page straight out of the Kernel API Manual, bestie, and it's called dwc3_free_one_event_buffer. Yes that's a mouthful, no I will not be shortening it, it's iconic as-is. 🎀

dwc3_free_one_event_buffer — literally frees one event buffer. that's it. that's the whole job. one buffer, freed, slay. 💅

🌸 SYNOPSIS 🌸

void dwc3_free_one_event_buffer (struct dwc3 *dwc , struct
       dwc3_event_buffer *evt );

notice the void? it returns nothing. no value, no gossip, no report back — it just does the thing and leaves. main character energy fr fr. 👑

🦋 ARGUMENTS 🦋

• dwc — the pointer to our controller context structure. like, our controller. the one we're vibing with. 🫶
• evt — the pointer to the event buffer that's getting freed. this is the one being let go. say your goodbyes. 😭
