Subject: lightnvm: Remove redundant rq->__data_len initialization
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=242e461fb628bb63763e0bb2788d52ea054f8721;p=openwrt%2Fstaging%2Fblogic.git

lightnvm: Remove redundant rq->__data_len initialization

Since both blk_old_get_request() and blk_mq_alloc_request() initialize
rq->__data_len to zero, it is not necessary to initialize that member
in nvme_nvm_alloc_request(). Hence remove the rq->__data_len
initialization from nvme_nvm_alloc_request().
