From 17ab7806de0c10d27cdbda8ef57ca680bdd24315 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 13 Jan 2017 18:36:30 +0100 Subject: [PATCH] drm: don't link DP aux i2c adapter to the hardware device node The i2c adapter on DP AUX is purely a software construct. Linking it to the device node of the parent device is wrong, as it leads to 2 devices sharing the same device node, which is bad practice, as well as the i2c trying to populate children of the i2c adapter by looking at the child device nodes of the parent device.
