Subject: [PATCH 47/51] drm/mipi-dbi: Move drm_mode_config_init into mipi library
Date: Mon, 23 Mar 2020 15:49:46 +0100	[thread overview]
Message-ID: <20200323144950.3018436-48-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200323144950.3018436-1-daniel.vetter@ffwll.ch>

7/7 drivers agree that's the right choice, let's do this.

This avoids duplicating the same old error checking code over all 7
drivers, which is the motivation here.
