From d281c862de30381c144145a75ec1f0d5efc307ae Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 21 Apr 2017 16:38:55 +0800 Subject: [PATCH] drm/sun4i: tcon: Copy ID from associated backend The tcons and backends have a one-to-one relationship. Their IDs, or indexes in the documentation, are also the same. Copy the ID from the associated backend and save it in the tcon structure. This will later be used when we add support for the output data path muxes.
