#ifdefs are comments. If you remove a contiguous sequence of things, the
comments between them disappear as well. If you add those things back,
the comments are gone. The idea is as follows:
@r@
identifier i;
expression e1;
@@
struct i2c_driver i = {
.driver = {
- .of_match_table=e1,
+ .of_match_table=of_match_ptr(e1),
},
};
@@
identifier r.i;
initialiser i1,i2;
@@
struct i2c_driver i = {
.driver = {
- i1,i2,
+ i1,i2,
},
};
@@
identifier r.i;
initialiser i1,i2,i3;
@@
struct i2c_driver i = {
.driver = {
- i1,i2,i3,
+ i1,i2,i3,
},
};
