Subject: Input: evdev - switch matching to EV_SYN
X-Git-Tag: v6.17-rc1~30^2^2~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=84060ea3e0b6294abde57b85502ccf9fa65f94de;p=thirdparty%2Fkernel%2Fstable.git

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.
