iio: adc: max1363: 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/) // <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@lip6.fr> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
