[PATCH v2 1/6] drm/i915/dsi: conversion to struct drm_device log macros.

Wambui Karuga
2020-01-22T11:08:57Z

This converts the more straightforward instances of the printk based
logging macros with the struct drm_device based logging macros.
This transformation was achieved using coccinelle and the following
script for matching an existing struct drm_i915_private device:
@rule1@
identifier fn, T;
@@

fn(...,struct drm_i915_private *T,...) {
<+...
(
-DRM_INFO(
+drm_info(&T->drm,

}

fn(...) {

}

New checkpatch warnings were fixed manually.
