Drop call to of_match_device, which is subsumed by the subsequent call to of_device_get_match_data. The code becomes simpler, and a temporary variable can be dropped. The semantic match that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ local idexpression match; identifier i; expression x, dev, e, e1; @@ - match@i = of_match_device(x, dev); - if (match) e = of_device_get_match_data(dev); - else e = e1; + e = of_device_get_match_data(dev); + if (!e) e = e1; @@ identifier r.i; @@ - const struct of_device_id *i; ... when != i // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/i2c/muxes/i2c-mux-pca954x.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/drivers/i2c/muxes/i2c-mux-pca954x.c b/drivers/i2c/muxes/i2c-mux-pca954x.c index 09bafd3..ced840f 100644 --- a/drivers/i2c/muxes/i2c-mux-pca954x.c +++ b/drivers/i2c/muxes/i2c-mux-pca954x.c @@ -373,7 +373,6 @@ static int pca954x_probe(struct i2c_client *client, int num, force, class; struct i2c_mux_core *muxc; struct pca954x *data; - const struct of_device_id *match; int ret; if (!i2c_check_functionality(adap, I2C_FUNC_SMBUS_BYTE)) @@ -394,10 +393,8 @@ static int pca954x_probe(struct i2c_client *client, if (IS_ERR(gpio)) return PTR_ERR(gpio); - match = of_match_device(of_match_ptr(pca954x_of_match), &client->dev); - if (match) - data->chip = of_device_get_match_data(&client->dev); - else + data->chip = of_device_get_match_data(&client->dev); + if (!data->chip) data->chip = &chips[id->driver_data]; if (data->chip->id.manufacturer_id != I2C_DEVICE_ID_NONE) { -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
