hid_match_usage(9)

✨ NAME ✨

okay so bestie, this is hid_match_usage(9) from the Kernel API Manual 💖 and it is literally here to check if driver's event should be called. no cap, that's the whole name-vibe.

🦋 SYNOPSIS 🦋

int hid_match_usage (struct hid_device *hid , struct hid_usage *usage );

🎀 ARGUMENTS 🎀

• hid — the hid device. that's it, that's the arg 🫶
• usage — the usage to match against. yes bestie, it is the usage you are matching.

💅 DESCRIPTION 💅

okay so the actual move is a lil compare. it compares hid->driver->usage_table->usage_{type,code} to usage->usage_{type,code}. that is the whole description, and honestly? iconic. the {type,code} bits are doing their little pair thing, and the function is checking them against each other. periodt. 💅
