[PATCH v2 5/6] drm/i915/opregion: conversion to struct drm_device logging macros.

Wambui Karuga
2020-01-22T11:09:11Z

This converts various instances of the printk based logging macros in
i915/display/intel_opregion.c with the new struct drm_device based
logging macros using the following coccinelle script:
@rule1@
identifier fn, T;
@@

fn(...,struct drm_i915_private *T,...) {

Checkpatch warnings were addressed manually.
