Subject: [PATCH v5 5/9] drm/rockchip: dw-mipi-dsi: Fix error handling path
Date: Wed, 18 Oct 2017 20:09:40 +0800	[thread overview]
Message-ID: <20171018120944.7819-6-jeffy.chen@rock-chips.com> (raw)
In-Reply-To: <20171018120944.7819-1-jeffy.chen@rock-chips.com>

Add missing pm_runtime_disable() in bind()'s error handling path.

Also cleanup encoder & connector in unbind().

Fixes: 80a9a059d4e4 ("drm/rockchip/dsi: add dw-mipi power domain support")
Signed-off-by: Jeffy Chen <jeffy.chen@rock-chips.com>
---

Changes in v5:
Call the destroy hook in the error handling path like in unbind().
