From 03ae3a9caf4a59edd32b65c89c375a98ce3ea1ef Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 25 Jun 2018 12:02:40 -0700 Subject: Input: psmouse - fix button reporting for basic protocols The commit ba667650c568 ("Input: psmouse - clean up code") was pretty brain-dead and broke extra buttons reporting for variety of PS/2 mice: Genius, Thinkmouse and Intellimouse Explorer. We need to actually inspect the data coming from the device when reporting events.
