From: Lucas Stach Date: Fri, 13 Jan 2017 17:36:30 +0000 (+0100) Subject: drm: don't link DP aux i2c adapter to the hardware device node X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=17ab7806de0c10d27cdbda8ef57ca680bdd24315;p=linux.git 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.
