    Subject[PATCH 5.10 524/717] media: ipu3-cio2: Remove traces of returned buffers
    Date
    From: Sakari Ailus <sakari.ailus@linux.intel.com>

    commit 61e7f892b5ee1dd10ea8bff805f3c3fe6e535959 upstream.

    If starting a video buffer queue fails, the buffers are returned to
    videobuf2. Remove the reference to the buffer from the driver's queue as
    well.
