[PATCH v1 2/6] gpiolib: acpi: Don't contaminate return parameter in case of error

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

If error occurs, leave lookup parameter untouched.

There is no functional change, since all current callers just bail out
in case of error without using the assigned pieces.
