lwmi_cd_sub_master_add(9)

💖 NAME 💖

Okay bestie, this page is lwmi_cd_sub_master_add(9) from the Kernel API Manual — and it’s literally about registering a sub-master with its sub-component. Slay. ✨

🌸 SYNOPSIS 🌸

int lwmi_cd_sub_master_add (struct lwmi_cd_priv *priv , enum
       lwmi_cd_type sub_component_type );

🎀 ARGUMENTS 🎀

• priv — Pointer to the sub-master capdata device private data. It’s giving “hand me the private-data bag, bestie.” 🫶
• sub_component_type — Type of the sub-component. Yep, that’s the whole vibe. 💅

🦋 DESCRIPTION 🦋

So here’s the tea: this function matches the sub-component type and registers the current capdata device as a sub-master. Main character registration moment, honestly. 👑

If the given sub-component type is CD_TYPE_NONE, it marks the sub-component as non-existent without registering the sub-master. No cap, no fake registration. 💀

⭐ RETURN ⭐

• 0 on success, or an error code. That’s it. That’s the return. Periodt. 💖
