Subject: [PATCH v5 04/25] drm: kirin: Remove uncessary parameter indirection
Date:   Tue, 20 Aug 2019 23:06:05 +0000
Message-Id: <20190820230626.23253-5-john.stultz@linaro.org>
In-Reply-To: <20190820230626.23253-1-john.stultz@linaro.org>
References: <20190820230626.23253-1-john.stultz@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Xu YiPing <xuyiping@hisilicon.com>

In a few functions, we pass in a struct ade_crtc, which we only
use to get to the underlying struct ade_hw_ctx.

Thus this patch refactors the functions to just take the
struct ade_hw_ctx directly.
