GCC would warn about this in the same manner but its version,
-Woverride-init, is disabled for a normal kernel build in
scripts/Makefile.warn. For clang, -Wextra in drivers/gpu/drm/Makefile
turns it back but GCC respects turning it off earlier in the command
line.
Of all the duplicate fields in the initializer, only nfl_bpg_offset is a
different value. Clear up the duplicate initializers, keeping the
'false' value for .vbr_enable, as it is bool, and the second value for
.nfl_bpg_offset, assuming it is the correct one since it was the one
tested in the original change.
