Subject[PATCH] drm/i915: convert to new logging macros based on struct intel_engine_cs.
Date
This patch extracts the struct drm_i915_private device from struct
intel_engine_cs and converts the printk based logging macros to the
struct drm_based logging macros using the extracted struct.
This transformation was achieved using the following coccinelle script:
@rule1@
identifier fn, T, E;
@@

fn(struct intel_engine_cs *T,...) {
struct drm_i915_private *E = ...;
