Good idea. :)
But while testing your patch it seems that it doesn't work as expected. 
Here some example:

w_scan version 20081106
Info: using DVB adapter auto detection.
   Found DVB-C frontend. Using adapter /dev/dvb/adapter0/frontend0
   Found DVB-C frontend. Using adapter /dev/dvb/adapter1/frontend0
   Found DVB-C frontend. Using adapter /dev/dvb/adapter2/frontend0
Info: unable to open frontend /dev/dvb/adapter3/frontend1'
Info: unable to open frontend /dev/dvb/adapter3/frontend2'
Info: unable to open frontend /dev/dvb/adapter3/frontend3'
-_-_-_-_ Getting frontend capabilities-_-_-_-_

I'm using three dvb-c frontends.
The detection doesnt stop anymore with your patch if a matching frontend 
was found, because it doesnt leave the outer loop.
Normally this search has to stop at /dev/dvb/adapter0/frontend0.
That means we have to change your patch a little. I also increased the 
number of adapters to 8, since i use more than 4.

Can you please test the attached patch and give some feedback? If it 
works fine for you, i would apply to w_scan.

PS: What is actually the maximum number of adapters and frontends per 
adapter? Can anybody give some hint?
