| [ Upstream commit b38d478dad79e61e8a65931021bdfd7a71741212 ] |
| |
| The Lenovo ThinkPad X1 Fold 16 Gen 1 has physical volume up/down |
| buttons that are handled through the intel-hid 5-button array |
| interface. The firmware does not advertise 5-button array support via |
| HEBC, so the driver relies on a DMI allowlist to enable it. |
| |
| Add the ThinkPad X1 Fold 16 Gen 1 to the button_array_table so the |
| volume buttons work out of the box. |
