[Intel-gfx] [PATCH v5 04/21] drm/i915/display/crt: Make WARN* drm specific where drm_priv ptr is available

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



drm specific WARN* calls include device information in the
backtrace, so we know what device the warnings originate from.

Covert all the calls of WARN* with device specific drm_WARN*
variants in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch.

func(...) {
...
struct drm_i915_private *T = ...;
<+...

-WARN(
+drm_WARN(&T->drm,
