Subject[PATCH AUTOSEL 4.14 101/108] blktrace: use errno instead of bi_status
Date
From: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>

[ Upstream commit 48bc3cd3e07a1486f45d9971c75d6090976c3b1b ]

In blk_add_trace_spliti() blk_add_trace_bio_remap() use
blk_status_to_errno() to pass the error instead of pasing the bi_status.
This fixes the sparse warning.
