[PATCH v2 2/6] drm/i915/ddi: convert to struct drm_device log macros.

2020-01-22T11:09:00Z

This patch converts various instances of the printk based logging macros
into the struct drm_device based macros. This was achieved using the
following coccinelle script for matching existing struct
drm_i915_private devices:
@rule1@
identifier fn, T;
@@

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

-DRM_INFO(
+drm_info(&T->drm,

}

Checkpatch warnings were addressed manually.
