Subject: [PATCH v1 3/7] drm: sti: make planes use atomic_print_state instead of debugfs
Date:   Tue,  5 Jun 2018 15:54:03 +0200
Message-Id: <20180605135407.20214-4-benjamin.gaignard@linaro.org>
In-Reply-To: <20180605135407.20214-1-benjamin.gaignard@linaro.org>
References: <20180605135407.20214-1-benjamin.gaignard@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Convert all sti planes to atomic_print_state usage rather than use a debugfs
entry.
