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