drivers: base: fw: fix ret value when loading fw
When using the user mode helper to load firmwares the function _request_firmware gets a positive return value from fw_load_from_user_helper and because of this the firmware buffer is not assigned. This happens only when the return value is zero. This patch fixes this problem in _request_firmware_load. When the completion is ready the return value is set to zero.
