Hi, This series includes some improvements around mtk_vcodec_mem_free() in mtk_vcodec_util.c. I noticed that mtk_vcodec_mem_free() generates a spurious error if the target DMA buffer has been freed previously: mtk_vcodec_mem_free(),69: [MTK_V4L2][ERROR] 18000000.video-codec dma_free size=0 failed! The warning is harmless, but it brings some confusion to our developers and testing infra, so I sent this series to fix that with some minor improvement for the driver alongside. The first two patches are for aesthetic and style improvements, the third tries to make the error logs more informative, and the last adds back the missing checks when calling the free function. Regards, Fei v1: https://lore.kernel.org/all/20231113123049.4117280-1-fshao@chromium.org/ Changes in v2: - rebased on top of next-20231219 - revise commit message for clearer intention and rationale - update the error messages based on the suggestion Fei Shao (4): media: mediatek: vcodec: Replace dev_name in error string media: mediatek: vcodec: Drop unnecessary variable media: mediatek: vcodec: Update mtk_vcodec_mem_free() error messages media: mediatek: vcodec: Only free buffer VA that is not NULL .../mediatek/vcodec/common/mtk_vcodec_util.c | 23 +++++++++---------- .../vcodec/decoder/vdec/vdec_av1_req_lat_if.c | 22 ++++++++++++------ .../vcodec/encoder/venc/venc_h264_if.c | 5 ++-- 3 files changed, 29 insertions(+), 21 deletions(-)
