[PATCH 03/11 v2] pinctrl: nomadik: use of_property_read_bool

From: Julia Lawall
Date: Fri Aug 05 2016 - 07:26:23 EST


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,x;
@@
- if (of_get_property(e1,e2,NULL))
- x = true;
- else
- x = false;
+ x = of_property_read_bool(e1,e2);
// </smpl>
