struct drm_device specific drm_WARN* macros include device information
in the backtrace, so we know what device the warnings originate from.
Prefer drm_WARN_ON over WARN_ON.
Conversion is done with below sementic patch:
@@
identifier func, T;
@@
func(...) {
...
struct intel_crtc *T = ...;
+struct drm_i915_private *dev_priv = to_i915(T->base.dev);
<+...
-WARN_ON(
+drm_WARN_ON(&dev_priv->drm,
...)
...+>
}

func(struct intel_crtc_state *T,...) {

<+...
-WARN_ON(
+drm_WARN_ON(&dev_priv->drm,
...)
...+>
}
changes since v1:
- Added dev_priv local variable and used it in drm_WARN_ON calls (Jani)
