--- Comment #4 from Stephen Hemminger <stephen at networkplumber dot org> ---
Agree that empty initializer is best for this driver.
But other information here.
The compile flags for this driver have disabled the warning.
cflags += '-Wno-maybe-uninitialized'
That might be related to the observed warnings.
