staging: comedi: usbdux: return void from usbdux_pwm_pattern()

Browse source

This function never fails and currently returns '1' so that the
usbdux_pwm_write() function returns to proper value (insn->n).

It's also called by usbdux_pwm_config() which also returns the '1'
value. The proper return code for this function should be '0' to
indicate success.

Change the return type of the function to void and just have the
callers return the proper values.
