mfd: palmas: Drop kfree of devm_kzalloc’s data
Author: Julia Lawall <Julia.Lawall@lip6.fr>
Using kfree to free data allocated with devm_kzalloc causes double frees.
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
//
@@
expression x;
@@
x = devm_kzalloc(...)
...
?-kfree(x);
//
