Subject: [PATCH][next] net: libwx: Replace zero-length array with flexible-array member

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Mon, 15 May 2023 13:23:46 -0600

Zero-length arrays as fake flexible arrays are deprecated, and we are
moving towards adopting C99 flexible-array members instead.

Transform zero-length array into flexible-array member in struct
wx_q_vector.
