A quirk was recently added for Elan devices that has same device match as an entry earlier in the list. The i2c_hid_lookup_quirk function will always return the last match in the list, so the new entry shadows the old entry. The quirk in the previous entry, I2C_HID_QUIRK_BOGUS_IRQ, silenced a flood of messages which have reappeared in the 5.13 kernel. This change moves the two quirk flags into the same entry.
