From 56d1b33e644cca1bedffbc73d28778ed4ae30f64 Mon Sep 17 00:00:00 2001 From: Antheas Kapenekakis Date: Thu, 22 Jan 2026 08:50:34 +0100 Subject: [PATCH] HID: asus: simplify RGB init sequence MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently, RGB initialization forks depending on whether a device is NKEY. However, in reality both initialization forks are the same, other than the NKEY initialization initializing the LED_REPORT_ID1, LED_REPORT_ID2 endpoints, and the non-NKEY initialization having a functionality check which is skipped for the NKEY path. Therefore, merge the if blocks, gate the ID1/ID2 initializations behind the NKEY quirk instead, and introduce the functionality check for NKEY devices (it is supported by them). There should be no functional change with this patch.
