From b80811546495ee7fd56d16b0fe978f3921f12175 Mon Sep 17 00:00:00 2001 From: Dafna Hirschfeld Date: Wed, 17 Nov 2021 14:06:34 +0100 Subject: [PATCH] media: mtk-vcodec: don't check return val of mtk_venc_get_q_data The function mtk_venc_get_q_data always returns a reference so there is no need to check if the return value is null. In addition move the q_data initialization to the declaration Signed-off-by: Dafna Hirschfeld Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c | 39 ++++------------------ 1 file changed, 7 insertions(+), 32 deletions(-) diff --git a/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c b/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c index 4357439..03f9055 100644 --- a/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c +++ b/drivers/media/platform/mtk-vcodec/mtk_vcodec_enc.c @@ -400,7 +400,7 @@ static int vidioc_venc_s_fmt_cap(struct file *file, void *priv, struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); const struct mtk_vcodec_enc_pdata *pdata = ctx->dev->venc_pdata; struct vb2_queue *vq; - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, f->type); int i, ret; const struct mtk_video_fmt *fmt; @@ -415,12 +415,6 @@ static int vidioc_venc_s_fmt_cap(struct file *file, void *priv, return -EBUSY; } - q_data = mtk_venc_get_q_data(ctx, f->type); - if (!q_data) { - mtk_v4l2_err("fail to get q data"); - return -EINVAL; - } - fmt = mtk_venc_find_format(f->fmt.pix.pixelformat, pdata); if (!fmt) { fmt = &ctx->dev->venc_pdata->capture_formats[0]; @@ -461,7 +455,7 @@ static int vidioc_venc_s_fmt_out(struct file *file, void *priv, struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); const struct mtk_vcodec_enc_pdata *pdata = ctx->dev->venc_pdata; struct vb2_queue *vq; - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, f->type); int ret, i; const struct mtk_video_fmt *fmt; @@ -476,12 +470,6 @@ static int vidioc_venc_s_fmt_out(struct file *file, void *priv, return -EBUSY; } - q_data = mtk_venc_get_q_data(ctx, f->type); - if (!q_data) { - mtk_v4l2_err("fail to get q data"); - return -EINVAL; - } - fmt = mtk_venc_find_format(f->fmt.pix.pixelformat, pdata); if (!fmt) { fmt = &ctx->dev->venc_pdata->output_formats[0]; @@ -521,14 +509,13 @@ static int vidioc_venc_g_fmt(struct file *file, void *priv, struct v4l2_pix_format_mplane *pix = &f->fmt.pix_mp; struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); struct vb2_queue *vq; - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, f->type); int i; vq = v4l2_m2m_get_vq(ctx->m2m_ctx, f->type); if (!vq) return -EINVAL; - q_data = mtk_venc_get_q_data(ctx, f->type); pix->width = q_data->coded_width; pix->height = q_data->coded_height; @@ -597,15 +584,11 @@ static int vidioc_venc_g_selection(struct file *file, void *priv, struct v4l2_selection *s) { struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, s->type); if (s->type != V4L2_BUF_TYPE_VIDEO_OUTPUT) return -EINVAL; - q_data = mtk_venc_get_q_data(ctx, s->type); - if (!q_data) - return -EINVAL; - switch (s->target) { case V4L2_SEL_TGT_CROP_DEFAULT: case V4L2_SEL_TGT_CROP_BOUNDS: @@ -631,15 +614,11 @@ static int vidioc_venc_s_selection(struct file *file, void *priv, struct v4l2_selection *s) { struct mtk_vcodec_ctx *ctx = fh_to_ctx(priv); - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, s->type); if (s->type != V4L2_BUF_TYPE_VIDEO_OUTPUT) return -EINVAL; - q_data = mtk_venc_get_q_data(ctx, s->type); - if (!q_data) - return -EINVAL; - switch (s->target) { case V4L2_SEL_TGT_CROP: /* Only support crop from (0,0) */ @@ -806,11 +785,9 @@ static int vb2ops_venc_queue_setup(struct vb2_queue *vq, struct device *alloc_devs[]) { struct mtk_vcodec_ctx *ctx = vb2_get_drv_priv(vq); - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, vq->type); unsigned int i; - q_data = mtk_venc_get_q_data(ctx, vq->type); - if (q_data == NULL) return -EINVAL; @@ -830,11 +807,9 @@ static int vb2ops_venc_queue_setup(struct vb2_queue *vq, static int vb2ops_venc_buf_prepare(struct vb2_buffer *vb) { struct mtk_vcodec_ctx *ctx = vb2_get_drv_priv(vb->vb2_queue); - struct mtk_q_data *q_data; + struct mtk_q_data *q_data = mtk_venc_get_q_data(ctx, vb->vb2_queue->type); int i; - q_data = mtk_venc_get_q_data(ctx, vb->vb2_queue->type); - for (i = 0; i < q_data->fmt->num_planes; i++) { if (vb2_plane_size(vb, i) < q_data->sizeimage[i]) { mtk_v4l2_err("data will not fit into plane %d (%lu < %d)", -- 2.7.4
