In current implementation, acpi_pcc_write_sset return 1 if write is successful, 0 if write is failed. But all the callers consider acpi_pcc_write_sset return 0 if write is successful and return negtive if write is failed.
This patch changes the implementation of acpi_pcc_write_sset to return 0 if write is successful, -EIO if write is failed.
