Subject: [PATCH] regulator: rpi-panel: Register with a unique
|
|
backlight name
|
|
|
|
There's no reason why 2 Raspberry Pi DSI displays can't be
|
|
attached to a Pi Compute Module, so the backlight names need to
|
|
be unique.
|
|
|
|
Use the parent dev_name. It's not as readable, but is unique.
