Subject: [PATCH 06/18] drm/i915/dsi: Move disable pll call outside of clear_device_ready()
Date: Thu,  1 Dec 2016 21:29:13 +0100	[thread overview]
Message-ID: <20161201202925.12220-7-hdegoede@redhat.com> (raw)
In-Reply-To: <20161201202925.12220-1-hdegoede@redhat.com>

On enable intel_dsi_enable() directly calls intel_enable_dsi_pll(),
make intel_dsi_disable() also directly call intel_disable_dsi_pll(),
rather then hiding the call in intel_dsi_clear_device_ready(),
no functional changes.
