Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit. Fix it by replacing with scnprintf().

Makes sense. Looks good to me!

Thanks for the patch (and review). Since this is a fix, I had to add
some "Fixes:" tags to the commit message. Since this is touching a
lot of lines added by a number of patches, it's a bit ugly. But, here
is what I added.
Fixes: fce8a7bb5b4b (PCI-Express Non-Transparent Bridge Support)
Fixes: 282a2feeb9bf (NTB: Use DMA Engine to Transmit and Receive)
Fixes: a754a8fcaf38 (NTB: allocate number transport entries depending on size of ring size)
Fixes: d98ef99e378b (NTB: Clean up QP stats info)
Fixes: e74bfeedad08 (NTB: Add flow control to the ntb_netdev)
Fixes: 569410ca756c (NTB: Use unique DMA channels for TX and RX)
I pulled it in to my ntb branch with the above change.
Thanks,
Jon
