ASoC: use of_property_read_bool
Use of_property_read_bool to check for the existence of a property. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e1,e2; statement S2,S1; @@ - if (of_get_property(e1,e2,NULL)) + if (of_property_read_bool(e1,e2)) S1 else S2 // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
