[PATCH 15/16] drivers/platform/x86: Use available error codes

[Julia Lawall]

From: Julia Lawall <julia@xxxxxxx>

An error code is stored in the variable error, but it is the variable
result that is returned instead.  So store the error code in result.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
local idexpression x;
constant C;
@@

if (...) { ...
  x = -C
  ... when != x
(
  return <+...x...+>;
|
  return NULL;
|
  return;
|
* return ...;
)
}
// </smpl>

Signed-off-by: Julia Lawall <julia@xxxxxxx>

This changes the semantics and has not been tested.  In each case, error is
also assigned to the result of a function call.  Perhpas that should be
changed to result as well, and error should be eliminated.
