🌸 NAME 🌸

ipc_imem_ul_write_td — the girl who takes your channel UL list, hands it over to the protocol layer so the TDs get prepped, and then gets them sent off to the device. basically a whole pipeline in one function, no cap 💅

🦋 SYNOPSIS 🦋

bool ipc_imem_ul_write_td (struct iosm_imem *ipc_imem );

one argument, one return, one iconic signature. periodt.

🎀 ARGUMENTS 🎀

• ipc_imem — a pointer to the imem data-struct. that's it, that's the whole input. she's low maintenance bestie 💖

---

⭐ RETURN ⭐

• TRUE — when the HP Doorbell trigger is pending 👑 (yes, HP Doorbell, capital letters, she's important)
• FALSE — in every other case, which is literally the definition of "otherwise" 😌
