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

Wambui Karuga
2020-01-22T11:09:14Z

Converts various instances of the printk based logging macros in
i915/display/intel_hdcp.c with the struct drm_device based macros using
coccinelle. The script matches based on the existence of an existing
struct drm_i915_private device:

New checkpatch warnings were addressed manually.
