The check of ezusb_firmware_download() return value (added by commit
488ec878034eccb852267b0e27ce9d511f75c587) is broken because
ezusb_firmware_download() returns 1 on success.
This causes the driver not to work with the following error:
orinoco_usb: probe of 3-3:1.0 failed with error -14
Check the return value only for negative values.
This fix should be applied to -stable kernels too.
