Subject: [PATCH 18/18] drm/armada: no need to check parent of remote
Date: Thu, 13 Jun 2019 16:03:14 +0100	[thread overview]
Message-ID: <E1hbRFy-000093-UZ@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20190613150114.xqkyb7j7w4ve4yvr@shell.armlinux.org.uk>

There's no need to check the parent of the remote device to check
whether it is available or not, the remote is the device itself.
