It is recommended to use driver model diagnostic macros dev_*() instead of raw printk() or pr_*() since the former ensures that the log messages are always associated with the corresponding device and driver. This also addresses the checkpatch complain for not using KERN_<LEVEL> facility in printk() call. Suggested-by: Fabio Aiuto <fabioaiuto83@xxxxxxxxx> Signed-off-by: Deepak R Varma <drv@xxxxxxxxx> --- Changes since v3: - use dev_dbg instead of dev_info since it spams less Changes since v2: - Tag Fabio Auito for the patch suggestion Changes in v1: - implement following changes suggested by Fabio Aiuto a. use dev_info instead of pr_info b. update patch log message accordingly .../media/atomisp/i2c/atomisp-gc0310.c | 30 +++++++++---------- 1 file changed, 15 insertions(+), 15 deletions(-) diff --git a/drivers/staging/media/atomisp/i2c/atomisp-gc0310.c b/drivers/staging/media/atomisp/i2c/atomisp-gc0310.c index b572551f1a0d..bb75d077ad63 100644 --- a/drivers/staging/media/atomisp/i2c/atomisp-gc0310.c +++ b/drivers/staging/media/atomisp/i2c/atomisp-gc0310.c @@ -300,7 +300,7 @@ static int gc0310_get_intg_factor(struct i2c_client *client, /* pixel clock calculattion */ dev->vt_pix_clk_freq_mhz = 14400000; // 16.8MHz buf->vt_pix_clk_freq_mhz = dev->vt_pix_clk_freq_mhz; - pr_info("vt_pix_clk_freq_mhz=%d\n", buf->vt_pix_clk_freq_mhz); + dev_dbg(&client->dev, "vt_pix_clk_freq_mhz=%d\n", buf->vt_pix_clk_freq_mhz); /* get integration time */ buf->coarse_integration_time_min = GC0310_COARSE_INTG_TIME_MIN; @@ -326,7 +326,7 @@ static int gc0310_get_intg_factor(struct i2c_client *client, if (ret) return ret; buf->crop_horizontal_start = val | (reg_val & 0xFF); - pr_info("crop_horizontal_start=%d\n", buf->crop_horizontal_start); + dev_dbg(&client->dev, "crop_horizontal_start=%d\n", buf->crop_horizontal_start); /* Getting crop_vertical_start */ ret = gc0310_read_reg(client, GC0310_8BIT, @@ -339,7 +339,7 @@ static int gc0310_get_intg_factor(struct i2c_client *client, if (ret) return ret; buf->crop_vertical_start = val | (reg_val & 0xFF); - pr_info("crop_vertical_start=%d\n", buf->crop_vertical_start); + dev_dbg(&client->dev, "crop_vertical_start=%d\n", buf->crop_vertical_start); /* Getting output_width */ ret = gc0310_read_reg(client, GC0310_8BIT, @@ -352,7 +352,7 @@ static int gc0310_get_intg_factor(struct i2c_client *client, if (ret) return ret; buf->output_width = val | (reg_val & 0xFF); - pr_info("output_width=%d\n", buf->output_width); + dev_dbg(&client->dev, "output_width=%d\n", buf->output_width); /* Getting output_height */ ret = gc0310_read_reg(client, GC0310_8BIT, @@ -365,12 +365,12 @@ static int gc0310_get_intg_factor(struct i2c_client *client, if (ret) return ret; buf->output_height = val | (reg_val & 0xFF); - pr_info("output_height=%d\n", buf->output_height); + dev_dbg(&client->dev, "output_height=%d\n", buf->output_height); buf->crop_horizontal_end = buf->crop_horizontal_start + buf->output_width - 1; buf->crop_vertical_end = buf->crop_vertical_start + buf->output_height - 1; - pr_info("crop_horizontal_end=%d\n", buf->crop_horizontal_end); - pr_info("crop_vertical_end=%d\n", buf->crop_vertical_end); + dev_dbg(&client->dev, "crop_horizontal_end=%d\n", buf->crop_horizontal_end); + dev_dbg(&client->dev, "crop_vertical_end=%d\n", buf->crop_vertical_end); /* Getting line_length_pck */ ret = gc0310_read_reg(client, GC0310_8BIT, @@ -389,7 +389,7 @@ static int gc0310_get_intg_factor(struct i2c_client *client, return ret; sh_delay = reg_val; buf->line_length_pck = buf->output_width + hori_blanking + sh_delay + 4; - pr_info("hori_blanking=%d sh_delay=%d line_length_pck=%d\n", hori_blanking, + dev_dbg(&client->dev, "hori_blanking=%d sh_delay=%d line_length_pck=%d\n", hori_blanking, sh_delay, buf->line_length_pck); /* Getting frame_length_lines */ @@ -404,7 +404,7 @@ static int gc0310_get_intg_factor(struct i2c_client *client, return ret; vert_blanking = val | (reg_val & 0xFF); buf->frame_length_lines = buf->output_height + vert_blanking; - pr_info("vert_blanking=%d frame_length_lines=%d\n", vert_blanking, + dev_dbg(&client->dev, "vert_blanking=%d frame_length_lines=%d\n", vert_blanking, buf->frame_length_lines); buf->binning_factor_x = res->bin_factor_x ?
