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.
