Subject: media: ov2680: Clear the 'ret' variable on success Author: Fabio Estevam <[email protected]> Date: Thu Mar 28 19:44:12 2024 -0300 Since commit 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint property verification") even when the correct 'link-frequencies' property is passed in the devicetree, the driver fails to probe: ov2680 1-0036: probe with driver ov2680 failed with error -22 The reason is that the variable 'ret' may contain the -EINVAL value from a previous assignment: ret = fwnode_property_read_u32(dev_fwnode(dev), "clock-frequency", &rate); Fix the problem by clearing 'ret' on the successful path. Tested on imx7s-warp board with the following devicetree: port { ov2680_to_mipi: endpoint { remote-endpoint = <&mipi_from_sensor>; clock-lanes = <0>; data-lanes = <1>; link-frequencies = /bits/ 64 <330000000>; }; }; Cc: [email protected] Fixes: 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint property verification") Suggested-by: Hans de Goede <[email protected]> Signed-off-by: Fabio Estevam <[email protected]> Reviewed-by: Hans de Goede <[email protected]> Signed-off-by: Sakari Ailus <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> drivers/media/i2c/ov2680.c | 1 + 1 file changed, 1 insertion(+) --- diff --git a/drivers/media/i2c/ov2680.c b/drivers/media/i2c/ov2680.c index 39d321e2b7f9..3e3b7c2b492c 100644 --- a/drivers/media/i2c/ov2680.c +++ b/drivers/media/i2c/ov2680.c @@ -1135,6 +1135,7 @@ static int ov2680_parse_dt(struct ov2680_dev *sensor) goto out_free_bus_cfg; } + ret = 0; out_free_bus_cfg: v4l2_fwnode_endpoint_free(&bus_cfg); return ret;
