Subject[PATCH 2/5] drm/i915/audio: convert to new drm logging macros.
Date
Converts the printk based logging macros in i915/display/intel_audio.c
to the struct drm_device based logging macros.
This transformation was achieved using the following coccinelle script
that matches the existence of the struct drm_i915_private device:

@rule1@
identifier fn, T;
@@

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

-DRM_INFO(
+drm_info(&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@

-DRM_DEBUG_KMS(
+drm_dbg_kms(&T->drm,

-DRM_DEBUG_DRIVER(

)

}

Checkpatch warnings were manually fixed.
