  • drm: Introduce struct drm_device based WARN* and use them in i915
Related show

Commit Message

Laxminarayan Bharadiya, Pankaj 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. checkpatch errors/warnings are fixed manually.
