hid_modify_dquirk(9)

okay bestie, welcome to the hid_modify_dquirk(9) page from the Kernel API Manual 💅✨ this one is literally about adding or replacing a HID quirk, and it's short but iconic.

🌸 NAME 🌸

hid_modify_dquirk — add/replace a HID quirk 🎀

✨ SYNOPSIS ✨

int hid_modify_dquirk (const struct hid_device_id *id , const unsigned
       long quirks );

🎀 ARGUMENTS 🎀

• id — the HID device to match 🫶
• quirks — the unsigned long quirks value to add/replace ⭐

💅 DESCRIPTION 💅

So picture this: if a dynamic quirk is already sitting in memory for this device, it gets its quirks value swapped out for the one you provided. Glow-up, basically. ✨

Otherwise? The quirk gets added to the dynamic quirks list. That's the whole vibe check. 💖

🔥 RETURN 🔥

Returns 0 for OK, or -error on failure. No cap. 💀
