combine into a single puts() ?

what's with the pointless cast ?  just do:
	strncpy(dfu->name, st, n);

also, "n" here is wrong.  it should be sizeof(dfu->name), not (presumably) the 
length of st.  considering this is the 2nd time i noticed this bug in the dfu 
patchset, you might want to do a grep on your patches to see if your other 
string related usage is wrong.

no point in assigning to NULL here
