Subject: staging: r8188eu: remove unused fields in struct recv_buf
X-Git-Tag: v6.1-rc5~1691^2~37
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=44aa511a6c383af3c9c858c38e078335d49d34f1;p=platform%2Fkernel%2Flinux-starfive.git

staging: r8188eu: remove unused fields in struct recv_buf

The fields alloc_sz, irp_pending and pallocated_buf in struct recv_buf
are set but not used. And the field dma_transfer_addr is not used.
Remove them.
