[PATCH 6/6] gpu: drm: omapdrm: displays: panel-dsi-cm: simplify getting .driver_data

From: Wolfram Sang
Date: Sun Oct 21 2018 - 16:00:25 EST


We should get 'driver_data' from 'struct device' directly. Going via
platform_device is an unneeded step back and forth.

Build tested only. buildbot is happy.
