Subject: [PATCH 2/3] drivers/mfd/palmas.c: drop kfree of devm_kzalloc's data

From: Julia Lawall <Julia.Lawall@...6.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/)

// <smpl>
@@
expression x;
@@

x = devm_kzalloc(...)
...
?-kfree(x);
// </smpl>
