[PATCH v2 0/1] drm: use drm_warn() in validate_blend_mode_for_alpha_formats()

Posted by Leandro Ribeiro 2 months ago

This replaces a WARN() with drm_warn() in
validate_blend_mode_for_alpha_formats().

The condition is expected to be triggered by existing drivers while they
adapt to the new blend mode requirement, so it should not use the kernel
warning report mechanism. WARN() output can cause fuzzers to stop when
they encounter a "WARNING:" message.

drm_warn() keeps the warning visible to driver developers without
triggering a WARN().

Changes in v2:
- Make the warning message more explicit
- Add a "Fixes" tag to commit
