Copy-paste error from the previous block of error handling code.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e,e1;
@@

if (IS_ERR(e)) {
  ...
(
  ret = PTR_ERR(e);
|
*  ret = PTR_ERR(e1);
)
  ...
  return ret;
}
// </smpl>

on STiH407 SoC family. It manages the powerdown signal,
and configures the internal glue logic and syscfg registers.
