From 84060ea3e0b6294abde57b85502ccf9fa65f94de Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 18 Feb 2025 15:09:21 -0800 Subject: [PATCH] Input: evdev - switch matching to EV_SYN Each input device has EV_SYN capability. This is enforced by the input core which sets this capability bit unconditionally in input_register_device(). Switch evdev matching from declaring non-zero id->driver_info to match on EV_SYN so that special handling can be removed from input_match_device() and "driver_info" field can be removed from input_device_id structure.
