✨ NAME ✨

qcom_submit_descs — submit dma descriptor 💅

---

🌸 SYNOPSIS 🌸

int qcom_submit_descs (struct qcom_nand_controller *nandc );

like, that's the whole signature. she's simple. she's iconic. she takes one (1) argument and hands you back an int. periodt. ⭐

🦋 ARGUMENTS 🦋

• nandc — the qpic nand controller, bestie. that's the vibe. that's who we're working with. 🫶

---

💖 DESCRIPTION 💖

so here's the tea ☕ — this function will submit all the prepared dma descriptor: cmd or data descriptor. all of 'em. no cap, not just one, all the prepared ones. 🔥

that's literally it, that's the whole function. lowkey obsessed with how straightforward she is. main character energy but make it a submit call. 👑
