[Xen-devel] new compile error in gx_comm.c in xen-unstable

[Olaf Hering <olaf@xxxxxxxxx>]

Hello,

there is a regression between xen-unstable rev 22314 and 22344,
gx_comm.c does not compile anymore due to -Werror, see below.
I think a simpe 'if (write(args..)) perror("write");' will be good enough.
