From 1d46c8e5c2702c141c6be982b3ca44e74d1cb8f1 Mon Sep 17 00:00:00 2001 From: Vladimir Kondratyev Date: Thu, 2 Nov 2023 09:20:20 +0300 Subject: [PATCH] hmt(4): Do not require input report HID usages to be a member of TLC Some touchpads places button usages (in HID report descriptor) in to the 2-nd level collection rather than in to the top level one. That confuses current code. Remove collection level check in HID report descriptor parser to fix device detection.
