Are you sure this is actually a variable length array?
It's not, it's just padding. We both told this in v1:
https://patchwork.kernel.org/project/linux-wireless/patch/20230731012941.21875-1-rauji.raut@xxxxxxxxx/
Hey, I'm consistent, nice! :)
But Atul, that's not good to ignore our review comments. Usually that
ends up meaning that everyone will then just ignore your submissions,
generally a not-good resolution.
thanks,

Since the 'pad' field is never directly accessed, suggest the author respin this this to use simply:
__le32 _pad;
That will prevent others from trying to "fix" this actual one-element array in the future.
