Subject: [PATCH v6 02/10] drm/rockchip: analogix_dp: Remove unnecessary init code
Date: Thu, 19 Oct 2017 11:48:04 +0800	[thread overview]
Message-ID: <20171019034812.13768-3-jeffy.chen@rock-chips.com> (raw)
In-Reply-To: <20171019034812.13768-1-jeffy.chen@rock-chips.com>

Remove unnecessary init code, since we would do it in the power_on()
callback.

Also move of parse code to probe().

Fixes: 9e32e16e9e98 ("drm: rockchip: dp: add rockchip platform dp driver")
Signed-off-by: Jeffy Chen <jeffy.chen@rock-chips.com>
