From 7fe565fb83ba7074dca1d25696f1d30116555528 Mon Sep 17 00:00:00 2001 From: Ionut Nechita Date: Wed, 7 Jan 2026 17:42:20 +0200 Subject: [PATCH] HID: asus: Filter spurious HID vendor codes on ROG laptops On Asus ROG laptops, several HID vendor usage codes (0xea, 0xec, 0x02, 0x8a, 0x9e) are sent during normal operation without a clear purpose, generating unwanted "Unmapped Asus vendor usagepage code" warnings in dmesg. Add definitions for these codes and filter them out in asus_raw_event() to prevent kernel log spam. Tested on Asus ROG series laptops.
