[Intel-gfx] [PATCH v4 4/4] drm/i915/gvt: Make WARN* drm specific where vgpu ptr is available
Pankaj Bharadiya
pankaj.laxminarayan.bharadiya at intel.com
Mon Jan 27 07:56:53 UTC 2020
Drm specific drm_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_device struct pointer is readily
available.
The conversion was done automatically with below coccinelle semantic
patch. checkpatch errors/warnings are fixed manually.
