[v5,14/21] drm/i915/display/overlay: Make WARN* drm specific where drm_priv ptr is available

Commit Message

Pankaj Bharadiya Jan. 28, 2020, 6:15 p.m. UTC

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.
