Transform the zero-length array in ath11k_htc_record into a proper

Why not removing the `union` and just do a direct transformation [0] -> [ ] ?
No reason other than staying consistent with ath10k.
Will see if Kalle has an opinion on this.
Yeah, I don't see the need for the union and I removed it in the pending
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=a2faeea1fe0635563187e7821a6d0baf7b40f2c6
Does it look ok?
Nope.
A direct transformation is just fine:
- union {
- struct ath11k_htc_credit_report credit_report[0];
- };
+ struct ath11k_htc_credit_report credit_report[];
There is no need for DFA in this situation.
Thanks
