[Xen-devel] [PATCH]Mini-OS: Small fix for NULL pointer handling

[Dietmar Hahn <dietmar.hahn@xxxxxxxxxxxxxxxxxxx>]

Hi Gregor,

attached is a small patch for netfront.c.
A compiler warning is fixed when -O? is used.
If the network is not configured, backend gets NULL from
xenbus_read() and this leads sometimes to a crash because this pointer is used 
later.
I hope this fix is OK. Please have a look and send comments!
Thanks.

Dietmar.
