[Intel-gfx] [PATCH v2 16/16] drm/edid: convert to device specific logging

Jani Nikula jani.nikula at intel.com
Mon Oct 24 12:33:44 UTC 2022


Convert to drm_kms_dbg/drm_err where possible, and reference the
connector using [CONNECTOR:%d:%s]. Pass connectors around a bit more to
enable this. Where this is not possible, unify the rest of the debugs to
DRM_DEBUG_KMS.

Rewrite tile debug logging to one line while at it.

v2:
- Use [CONNECTOR:%d:%s] throughout (Ville)
- Tile debug logging revamp
- Pass connector around a bit more
