Subject: drm/amd/display: Refine error message for vblank init failure
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3b14fe98939b01aa72707bc3c2617de319839a65;p=users%2Fhch%2Fmisc.git

drm/amd/display: Refine error message for vblank init failure

[Why]
The error message "failed to initialize sw for display support" is used
for both DRM device and vblank initialization failures, making it difficult
to identify the specific failure during troubleshooting.

[How]
Update the vblank initialization error message to
"failed to initialize vblank for display support"
to distinguish it from the DRM device init failure.
