Subject: [PATCH 06/26] drm: sun4i: Use the dev_pm_ops provided by modeset helper
Date:   Mon,  7 Nov 2022 17:50:46 +0000
Message-Id: <20221107175106.360578-7-paul@crapouillou.net>
In-Reply-To: <20221107175106.360578-1-paul@crapouillou.net>
References: <20221107175106.360578-1-paul@crapouillou.net>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use the drm_mode_config_pm_ops structure exported by
drm_modeset_helper.c, which provides the exact same PM callbacks.
