[PATCH 02/12] drm/i915/vlv_dsi: conversion to drm_device based logging macros.

From: Wambui Karuga
Date: Thu Jan 30 2020 - 03:32:46 EST


Converts the printk based logging macros to the struct drm_device based
logging macros in i915/display/vlv_dsi.c.
This was done using the following coccinelle script that transforms
based on the existence of a drm_i915_private device pointer.

Checkpatch warnings were addressed manually.
