Subject: [PATCH resend 04/15] drm/i915/dsi: Move intel_dsi_clear_device_ready()
Date: Mon, 20 Feb 2017 15:08:34 +0100	[thread overview]
Message-ID: <20170220140845.1714-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20170220140845.1714-1-hdegoede@redhat.com>

Move the intel_dsi_clear_device_ready() function to higher up in
intel_dsi.c this pairs it with intel_dsi_device_ready(); and pairs
intel_dsi_*enable* with intel_dsi_*disable without
intel_dsi_clear_device_ready() sitting in the middle of them.

This commit purely moves code around, it does not make any
changes what-so-ever.
