The core does clear the reserved field from v4l2_pix_format_mplane, but not the reserved field for every plane. I can try to add it to the core as well. At least these drivers have code duplication: git grep reserved | grep memset | grep plane_fmt drivers/media/pci/intel/ipu3/ipu3-cio2.c: memset(mpix->plane_fmt[0].reserved, 0, drivers/media/platform/mtk-mdp/mtk_mdp_m2m.c: memset(pix_mp->plane_fmt[i].reserved, 0, drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c: memset(&(pix_fmt_mp->plane_fmt[i].reserved[0]), 0x0, drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c: memset(&(pix_fmt_mp->plane_fmt[i].reserved[0]), 0x0, drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c: memset(&(pix->plane_fmt[i].reserved[0]), 0x0, drivers/media/platform/rcar_fdp1.c: memset(pix->plane_fmt[i].reserved, 0, drivers/media/platform/rcar_fdp1.c: memset(pix->plane_fmt[2].reserved, 0, drivers/media/platform/rcar_jpu.c: memset(pix->plane_fmt[0].reserved, 0, drivers/media/platform/rcar_jpu.c: memset(pix->plane_fmt[i].reserved, 0, drivers/media/platform/sunxi/sun4i-csi/sun4i_v4l2.c: memset(pix->plane_fmt[i].reserved, 0, drivers/media/platform/ti-vpe/vpe.c: memset(plane_fmt->reserved, 0, sizeof(plane_fmt->reserved)); drivers/media/test-drivers/vicodec/vicodec-core.c: memset(pix_mp->plane_fmt[0].reserved, 0, drivers/staging/media/hantro/hantro_v4l2.c: memset(pix_mp->plane_fmt[i].reserved, 0, drivers/staging/media/ipu3/ipu3-v4l2.c: memset(pixm->plane_fmt[0].reserved, 0, > > Thanks, > Ezequiel > -- Ricardo Ribalda _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
