Subject: [PATCH 3/9] staging: r8188eu: remove unused fields in struct recv_buf
Date:   Thu,  3 Mar 2022 21:21:05 +0530
Message-Id: <fe5565c02a01babf64469333dae73cbdd841d393.1646321515.git.abdun.nihaal@gmail.com>

Precedence: bulk

The fields len, ref_cnt and transfer_len in struct recv_buf are set
but not used. Remove them.
