Subject[PATCH 4/5] drm/i915/bw: convert to new drm_device based logging macros.
Date
This replaces the printk based logging macros with the struct drm_based
macros in i915/display/intel_bw.c
This transformation was achieved by using the following coccinelle
script that matches based on the existence of a struct drm_i915_private
device in the functions:

@rule1@
identifier fn, T;
@@

fn(struct drm_i915_private *T,...) {
<+...
(
-DRM_INFO(
+drm_info(&T->drm,
...)
|
-DRM_ERROR(
+drm_err(&T->drm,
...)
|
-DRM_WARN(
+drm_warn(&T->drm,
...)
|
-DRM_DEBUG(
+drm_dbg(&T->drm,
...)
|
-DRM_DEBUG_DRIVER(
+drm_dbg(&T->drm,
...)
|
-DRM_DEBUG_KMS(
+drm_dbg_kms(&T->drm,
...)
)
...+>
}

@rule2@
identifier fn, T;
@@

fn(...) {
...
struct drm_i915_private *T = ...;
<+...
(
-DRM_INFO(
+drm_info(&T->drm,
...)
|
-DRM_ERROR(
+drm_err(&T->drm,
...)
|
-DRM_WARN(
+drm_warn(&T->drm,
...)
|
-DRM_DEBUG(
+drm_dbg(&T->drm,
...)
|
-DRM_DEBUG_KMS(
+drm_dbg_kms(&T->drm,
...)
|
-DRM_DEBUG_DRIVER(
+drm_dbg(&T->drm,
...)
)
...+>
}

Resulting checkpatch warnings were addressed manually.
