Series drm/i915: Introduce i915 based i915_MISSING_CASE macro and us it in i915 | expand

Commit Message

Pankaj Bharadiya Feb. 25, 2020, 1:47 p.m. UTC 
i915_MISSING_CASE macro includes the device information in the
backtrace, so we know what device the warnings originate from.

Covert MISSING_CASE calls with i915 specific i915_MISSING_CASE variant
in functions where drm_i915_private struct pointer is readily
available.

The conversion was done automatically with below coccinelle semantic
patch.
