Subject: [PATCH 1/9] regulator: rpi-panel: Register with a unique backlight name
Date: Thu, 20 Jan 2022 10:21:42 -0500 [thread overview]
Message-ID: <20220120152150.1952568-2-detlev.casanova@collabora.com> (raw)
In-Reply-To: <20220120152150.1952568-1-detlev.casanova@collabora.com>
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.
