Subject: [PATCH v3 1/7] drm/i2c: tda998x: move mutex/waitqueue/timer/work init early
Date: Mon, 09 Apr 2018 13:16:12 +0100	[thread overview]
Message-ID: <E1f5ViW-0002LF-BQ@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20180409121529.GA31403@n2100.armlinux.org.uk>

Move the mutex, waitqueue, timer and detect work initialisation early
in the driver's initialisation, rather than being after we've registered
the CEC device.

Acked-by: Hans Verkuil <hans.verkuil@cisco.com>
