If the heatshrink on the controller is melted/distorted and the smoke came from there, you could have damaged one or more of the FETs. The controller could still technically work (if the bad FETs "opened" when they smoked), but there are a bunch of FETs in parallel so if you smoke one/some, then the others will be forced to work harder and will heat up more.

IMHO, I wouldn't run it until it's fixed. Running it as-is will just shorten the life of the remaining FETs.
