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. checkpatch errors/warnings are fixed manually. @rule1@ identifier func, T; @@ func(...) { ... struct drm_i915_private *T = ...; <+...
