From b10d7a1fd6fcb16f242ffbd87bf0466b337708d6 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 May 2018 11:49:08 +0200 Subject: i2c: mux: pca954x: merge calls to of_match_device and of_device_get_match_data 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/) // @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 // Signed-off-by: Julia Lawall Signed-off-by: Peter Rosin --- drivers/i2c/muxes/i2c-mux-pca954x.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'drivers/i2c/muxes/i2c-mux-pca954x.c') diff --git a/drivers/i2c/muxes/i2c-mux-pca954x.c b/drivers/i2c/muxes/i2c-mux-pca954x.c index fe20b8ec5247..fbc748027087 100644 --- a/drivers/i2c/muxes/i2c-mux-pca954x.c +++ b/drivers/i2c/muxes/i2c-mux-pca954x.c @@ -374,7 +374,6 @@ 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)) @@ -401,10 +400,8 @@ static int pca954x_probe(struct i2c_client *client, udelay(1); } - 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) { -- cgit
