Subject: drm/i915/display/crt: Make WARN* drm specific where drm_priv ptr is
Git-commit: 6a79c28936dfc44019d42e36aaf8acd9c38f66c2
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
available
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.
