💖 lwmi_cd_match_add_all(9) — Kernel API Manual, bestie 💖

okay so welcome to the Kernel API Manual page for lwmi_cd_match_add_all(9), and she is serving “add all the match rules for the master driver” realness. no cap, this one’s a tiny function with big component-match energy 🫶

🌸 NAME 🌸

lwmi_cd_match_add_all — Add all match rule for the master driver. periodt. 💅

✨ SYNOPSIS ✨

void lwmi_cd_match_add_all (struct device *master , struct
       component_match **matchptr );

🎀 ARGUMENTS 🎀

• master — pointer to the master device. that’s the main-character device in this situation 👑
• matchptr — pointer to the returned component_match pointer. yes bestie, a pointer to a pointer; the matching list lives through it 🦋

🦋 DESCRIPTION 🦋

okay so what she does: lwmi_cd_match_add_all adds all component matches to the list stored in matchptr for the master device. it’s giving “collect every match, put them in the list, done” ✨

⚠️ real talk: matchptr must be initialized to NULL. this is not a vibe-check-optional situation; initialize it to NULL, bestie 😭
