Reformat example code to match libftdi style:

[libftdi] / libftdi.lnt

// PC-Lint 9.00 settings

-emacro(527, ftdi_error_return)     // ignore "unreachable code"
-emacro(717, ftdi_error_return)

-epu // Pointer to unsigned/signed of the same type is ok

+fie // Allow enum to int conversion

-ecall(534, usb_close)              // silence ignored return value from usb_close
