It's not as common as people think for a broker to exercise the other part of the spread automatically (unless it is very close to expiration). 
  
 Long stock + long put is a defined risk position (and exercising the put leaves you at max risk), so it isn't all that risky provided that you aren't close to expiration. In fact, in some cases you can sell the shares and then sell to close the long put and (occasionally) capture a small amount of extrinsic value.

Long stock + long put = short call, right? 
  
 Edit: Nvm, long call.
