okay bestie, welcome to the Kernel API Manual page for dwc3_ep_inc_trb(9) — tiny function, big main-character energy. let's go. ✨

💖 NAME 💖

dwc3_ep_inc_trb — increment a trb index. that's the whole name, no cap. 💫

🌸 SYNOPSIS 🌸

void dwc3_ep_inc_trb (u8 *index );

🫶 ARGUMENTS 🫶

• index — pointer to the TRB index to increment. yes, that's the one. 🎀

🔥 DESCRIPTION 🔥

okay so the vibe check here is: index should never point to the link TRB. like, that is not the move. 🙈

after incrementing, if it's pointing to the link TRB, wrap around to the beginning. the link TRB is always at the last TRB entry. slay, that's the wrap-around, periodt. 💅
