[Bluez-devel] Small bugfix for dund

[Bluez-devel] Small bugfix for dund

[Ludovic Drolez]

Hi !

Sometimes, dund fails with the following error:
 dund[15658]: RFCOMM TTY creation failed. No such file or directory(2)

That's because, udev does not have the time to create the device.
I've found in dund's code that dund waits, at most, 30*100us for the device to
become readable. I think that the author made a typo here, and that 30*100ms is
much more appropriate (see the patch below).

Cheers,

   Ludovic.

same issue is in rfcomm/main.c. I fixed both now. Thanks.
