Subject: md: Make bio_alloc_mddev use bio_alloc_bioset
X-Git-Tag: v5.4-rc1~1718^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6251691a92170d3a781aaf7b5f2c31b50d669809;p=platform%2Fkernel%2Flinux-rpi.git

md: Make bio_alloc_mddev use bio_alloc_bioset

bio_alloc_bioset returns a bio pointer or NULL, so we can avoid storing
the returned data into a new variable.
