mpt_deregister(9)

💅 mpt_deregister — Kernel API Manual (section 9)

okay bestie, this page lives in the Kernel API Manual, section 9, and it’s short enough to read while your module unloads. no cap, it’s giving “tiny cleanup queen” energy. 🎀

🌸 NAME 🌸

mpt_deregister — deregister a protocol drivers resources. that’s the official phrase, and I’m not fixing the grammar, I’m just delivering the facts. 💅

✨ SYNOPSIS ✨

void mpt_deregister (u8 cb_idx );

🎀 ARGUMENTS 🎀

• cb_idx — the previously registered callback handle. that’s the whole argument, bestie. 🫶

💖 DESCRIPTION 💖

Each protocol-specific driver should call this routine when its module is unloaded. so when your module is saying bye, this is the routine it should hit up. literally the unload-time bestie. 🔥
