Subject: [PATCH v2 0/2] media: uvcvideo: Avoid partial metadata buffers
Date: Fri, 17 Apr 2026 05:19:27 +0000 [thread overview]
Message-ID: <20260417-uvc-meta-partial-v2-0-31d274af7d2d@chromium.org> (raw)
The current code can lead to partial metadata buffers when the metadata
queue transitions from empty to ready. Fix that.
Signed-off-by: Ricardo Ribalda <ribalda@chromium.org>

Changes in v2: (Thanks Laurent)
- Transition to UVC_BUF_STATE_ACTIVE with the data buffer
- Link to v1: https://lore.kernel.org/r/20260415-uvc-meta-partial-v1-0-a0acc79a6300@chromium.org
