From 68c3f904ed4591797ccac22148b95c54af391f30 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 28 Jun 2018 08:31:28 -0700 Subject: [PATCH] scsi: sd_zbc: Remove an assignment from sd_zbc_setup_report_cmnd() Since nr_bytes == blk_rq_bytes(rq) == rq->__data_len, the rq->__data_len = nr_bytes assignment does not modify the value of rq->__data_len. Hence remove that assignment. Note: the code in sd_done() that sets the residual to zero for zone report requests is not affected by this patch.
