Subject: [PATCH 06/17] imx/drm: parallel-display: split attach function
Date: Thu, 27 Feb 2020 17:21:14 +0100	[thread overview]
Message-ID: <20200227162125.10450-7-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20200227162125.10450-1-m.felsch@pengutronix.de>

Split the maybe failing attach function from imx_pd_register() so we
can construct simple error paths later on.
