gpio: wcove: Allow return negative error code from to_reg()
The type of to_reg() is unsigned int while it might return a negative error code. Callers are also expecting a signed type. For sake of type consistency replace unsigned int with plain int. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
