From f6d8378065c69a88ece68523320b9b59c156aafc Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Thu, 11 Feb 2021 18:46:06 +0000 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.
