[PATCH 5.13 183/380] media: hantro: vp8: Move noisy WARN_ON to vpu_debug

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx>

[ Upstream commit 6ad61a7847da09b6261824accb539d05bcdfef65 ]

When the VP8 decoders can't find a reference frame,
the driver falls back to the current output frame.

This will probably produce some undesirable results,
leading to frame corruption, but shouldn't cause
noisy warnings.
