Fixes: 89aef879cb53 ("media: i2c: Add support for ov5693 sensor") Signed-off-by: Christophe JAILLET --- Sometimes, some people complain that dev_err_probe() calls should be limited to probe functions and functions called from probe. So maybe this should be converted to a plain dev_err(). Personally I don't fully agree. dev_err_probe() also has the advantage of not being a macro and avoids some inlining. So it can help to prevent the filling of the instruction cache of the processor with things unlikely to be needed. --- drivers/media/i2c/ov5693.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/media/i2c/ov5693.c b/drivers/media/i2c/ov5693.c index 82a9b2de7735..8cf9516b6d57 100644 --- a/drivers/media/i2c/ov5693.c +++ b/drivers/media/i2c/ov5693.c @@ -403,8 +403,8 @@ static int ov5693_read_reg(struct ov5693_device *ov5693, u32 addr, u32 *value) ret = i2c_transfer(client->adapter, msg, 2); if (ret < 0) return dev_err_probe(&client->dev, ret, - "Failed to read register 0x%04x: %d\n", - addr & OV5693_REG_ADDR_MASK, ret); + "Failed to read register 0x%04x\n", + addr & OV5693_REG_ADDR_MASK); *value = 0; for (i = 0; i < len; ++i) {
