Subject: [resend PATCH v4 5/5] drm: mediatek: Omit warning on probe defers
Date: Wed, 18 Jul 2018 00:03:28 +0200	[thread overview]
Message-ID: <20180717220328.792-6-matthias.bgg@kernel.org> (raw)
In-Reply-To: <20180717220328.792-1-matthias.bgg@kernel.org>

From: Matthias Brugger <mbrugger@suse.com>

It can happen that the clock drivers wasn't probed before the
ddp driver gets invoked. The driver used to omit a warning
that the driver failed to get the clocks. Omit this error on
the defered probe path.
