The warning is annoying in many ways. You ought to be able to zero initialise
any struct with {0}, but clang objects if you do this and requires every field
to be filled in. This warning really shouldn’t be enabled with -Wall, because
it has too hight a false positive rate.
With regard to Bruce’s comment about padding, this is a known issue in C11.
There is an open DR about it and it’s scheduled for discussion at the WG14
meeting in London in April.
