From 9576af6a95dbabd035a59fa6ffc5b88baa07f221 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 22 Mar 2019 08:41:38 +0100 Subject: [PATCH] HID: logitech-hidpp: simplify printing of HID++ version Simply always print the HID++ version on hidpp_root_get_protocol_version success. This also fixes the version not being printed when a HID++ device connected through a receiver is already connected when the hidpp driver is loaded.
