[Asterisk-bsd] app_dahdiscan.c: Unable to set flags: Inappropriate ioctl for device

[michel]

 Hello, dahdiscan isn't working on my system (freebsd 7.2). It generates 
this error:
"app_dahdiscan.c: Unable to set flags: Inappropriate ioctl for device"
The reason seems to be the same as in bug 0014482 
https://issues.asterisk.org/view.php?id=14482
I made this litle patch and thought it may be useful to someone else.
Michel
