[PATCH v2 2/3] wifi: mwifiex: Replace one-element array with flexible-array member in struct mwifiex_ie_types_rxba_sync
From: Gustavo A. R. Silva
Date: Thu Aug 24 2023 - 23:07:36 EST
One-element and zero-length arrays are deprecated. So, replace
one-element array in struct mwifiex_ie_types_rxba_sync with
flexible-array member, and refactor the rest of the code, accordingly.
This results in no differences in binary output.
