| Subject: [PATCH 0788/1795] regulator: giving regulator controlling gpios a |
| non-empty label when used through the devicetree. |
| |
| When the label is empty, it causes missing information and limits diagnostics |
| for instances such as 'cat /sys/kernel/debug/gpio' |
| |
| Setting the label to the regulator supply_name will point to the device |
| using the gpio(s). |
