From: Gert Wollny <gert.wol...@collabora.com>
This warning is misleading: When a struct is partially initialized without
assigning to the struture members by name, then the un-initialized fields
will be zeroed out, and this warning will be issued (if enabled). If, on the
other hand, the partial initialization is done by assigning to named members,
the remaining structure elements may hold random data, but the warning is not
issued. Since in Mesa the first approach to initialize structure elements is
used very often, and it is usually assumed that the remaining elements are
zeroed out, so heeding this warning would be counter-productive.
v2: - add -Wno-missing-field-initializers to meson-build
- fix empty line error
