Subject: media: fsl-viu: mark static functions as such Author: Mauro Carvalho Chehab <[email protected]> Date: Thu Apr 5 10:24:43 2018 -0400 There are several functions that are used only inside the driver. Stop exposing that to global symbolspace. Get rid of the following gcc warnings: drivers/media/platform/fsl-viu.c:240:17: warning: no previous prototype for ‘format_by_fourcc’ [-Wmissing-prototypes] struct viu_fmt *format_by_fourcc(int fourcc) ^~~~~~~~~~~~~~~~ drivers/media/platform/fsl-viu.c:253:6: warning: no previous prototype for ‘viu_start_dma’ [-Wmissing-prototypes] void viu_start_dma(struct viu_dev *dev) ^~~~~~~~~~~~~ drivers/media/platform/fsl-viu.c:262:6: warning: no previous prototype for ‘viu_stop_dma’ [-Wmissing-prototypes] void viu_stop_dma(struct viu_dev *dev) ^~~~~~~~~~~~ drivers/media/platform/fsl-viu.c:807:5: warning: no previous prototype for ‘vidioc_g_fbuf’ [-Wmissing-prototypes] int vidioc_g_fbuf(struct file *file, void *priv, struct v4l2_framebuffer *arg) ^~~~~~~~~~~~~ drivers/media/platform/fsl-viu.c:818:5: warning: no previous prototype for ‘vidioc_s_fbuf’ [-Wmissing-prototypes] int vidioc_s_fbuf(struct file *file, void *priv, const struct v4l2_framebuffer *arg) ^~~~~~~~~~~~~ drivers/media/platform/fsl-viu.c: In function ‘viu_open’: drivers/media/platform/fsl-viu.c:1170:6: warning: variable ‘status_cfg’ set but not used [-Wunused-but-set-variable] u32 status_cfg; ^~~~~~~~~~ drivers/media/platform/fsl-viu.c: At top level: drivers/media/platform/fsl-viu.c:1304:6: warning: no previous prototype for ‘viu_reset’ [-Wmissing-prototypes] void viu_reset(struct viu_reg *reg) ^~~~~~~~~ Signed-off-by: Mauro Carvalho Chehab <[email protected]> drivers/media/platform/fsl-viu.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) --- diff --git a/drivers/media/platform/fsl-viu.c b/drivers/media/platform/fsl-viu.c index 200c47c69a75..9abe79779659 100644 --- a/drivers/media/platform/fsl-viu.c +++ b/drivers/media/platform/fsl-viu.c @@ -229,7 +229,7 @@ enum status_config { static irqreturn_t viu_intr(int irq, void *dev_id); -struct viu_fmt *format_by_fourcc(int fourcc) +static struct viu_fmt *format_by_fourcc(int fourcc) { int i; @@ -242,7 +242,7 @@ struct viu_fmt *format_by_fourcc(int fourcc) return NULL; } -void viu_start_dma(struct viu_dev *dev) +static void viu_start_dma(struct viu_dev *dev) { struct viu_reg *vr = dev->vr; @@ -253,7 +253,7 @@ void viu_start_dma(struct viu_dev *dev) out_be32(&vr->status_cfg, INT_FIELD_EN); } -void viu_stop_dma(struct viu_dev *dev) +static void viu_stop_dma(struct viu_dev *dev) { struct viu_reg *vr = dev->vr; int cnt = 100; @@ -802,7 +802,7 @@ static int vidioc_overlay(struct file *file, void *priv, unsigned int on) return 0; } -int vidioc_g_fbuf(struct file *file, void *priv, struct v4l2_framebuffer *arg) +static int vidioc_g_fbuf(struct file *file, void *priv, struct v4l2_framebuffer *arg) { struct viu_fh *fh = priv; struct viu_dev *dev = fh->dev; @@ -813,7 +813,7 @@ int vidioc_g_fbuf(struct file *file, void *priv, struct v4l2_framebuffer *arg) return 0; } -int vidioc_s_fbuf(struct file *file, void *priv, const struct v4l2_framebuffer *arg) +static int vidioc_s_fbuf(struct file *file, void *priv, const struct v4l2_framebuffer *arg) { struct viu_fh *fh = priv; struct viu_dev *dev = fh->dev; @@ -1305,7 +1305,7 @@ static int viu_release(struct file *file) return 0; } -void viu_reset(struct viu_reg *reg) +static void viu_reset(struct viu_reg *reg) { out_be32(®->status_cfg, 0); out_be32(®->luminance, 0x9512a254); _______________________________________________ linuxtv-commits mailing list [email protected] https://www.linuxtv.org/cgi-bin/mailman/listinfo/linuxtv-commits
