I see this right above:
if (attrs->DMABufPlaneFds[i].IsPresent ||
attrs->DMABufPlaneOffsets[i].IsPresent ||
attrs->DMABufPlanePitches[i].IsPresent ||
attrs->DMABufPlaneModifiersLo[i].IsPresent ||
attrs->DMABufPlaneModifiersHi[i].IsPresent) {
If modifiers are present, this is always true, regardless of whether the
fd is present.
The loop that checks for fd presence even before that only loops up to
the number of planes determined by the non-modified fourcc.
