That can't work in this context. Did you even try to compile?

.../dibusb-mb.c:178: warning: excess elements in array initializer
.../dibusb-mb.c:178: warning: (near initialization for `dibusb1_1_properties.devices')

The solution below wastes a few 100 bytes of space, but I think we can
live with that. The same thing was done in dvb-pll.h.
gcc-2.95 compile fix.
