why? only because most other drivers use the same initialzisation for
their static array for device name and because I didn't know
(and wasn't sure) that it's guaranteed [for all time] that these
arrays are initialized with zero. as my problem showed, it's
important that they _are_ initialized, so I thought better be sure...

hmm, non-writable strings would hit quite a number of network driver modules
at this point...
