Subject: [PATCH 1/9] regulator: rpi-panel: Register with a unique backlight name
From: Dave Stevenson <dave.stevenson@...pberrypi.com>
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.
