If anyone has any objections, please let me know. ------------------ From: Nikolay Metchev [ Upstream commit c39023ca9a447f09c072080efc84d6874c2275c9 ] The volume rocker buttons on the HP ProBook x360 440 G1 convertible emit events 0xc4-0xc7 via the intel-hid ACPI device (INT33D5). These codes are only present in intel_array_keymap, which is used when the "5 button array" input device exists. On this machine button_array_present() returns false because the firmware does not advertise the array through the HEBC method, so notify_handler() routes the events to a NULL priv->array and they are dropped as "unknown event 0xc4". As a result the side volume keys do nothing. Add the machine to button_array_table so the array device is created and the volume rocker emits KEY_VOLUMEUP / KEY_VOLUMEDOWN. This is equivalent to booting with the enable_5_button_array=1 module parameter, which was used to confirm the fix on the affected hardware.
