Subject: [v3 09/10] drm: mediatek: Omit warning on probe defers
Date: Fri, 27 Apr 2018 11:24:01 +0200 [thread overview]
Message-ID: <9d514a4ab45f0700663fa756d5aa3913922b6fb7.1524820923.git.mbrugger@suse.com> (raw)
In-Reply-To: <cover.1524820923.git.mbrugger@suse.com>
In-Reply-To: <cover.1524820923.git.mbrugger@suse.com>
From: Matthias Brugger <mbrugger@suse.com>
When probe through the MFD, 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.
